Digital Rotary Torque Sensor, 0.1/5/300/1000 Nm to 10000 Nm

I am in the process of setting up communication with the device and going to go through using the software. However, I was curious if you have any C code that can talk to the device directly and print a data stream of torque and RPM. Also, when connecting this device via half duplex, do you include the signal ground? The USB to RS-485 converter documentation shows that a ground connection is needed. I wanted to make sure that the signal ground was the appropriate connection.

I have a DYN200 torque sensor. The 4-20 torque signal works perfectly. I cannot get a speed signal on the orange grey wires. Can you please advise.

The digital display shows 0 Nm correctly, but when we connect a current meter to the Green & White wires (Sig + and Sig -) of the torque sensor, it reads 10 mA. Our setup involves powering the torque sensor with 24V, and the Sig + and Sig - wires are connected to a 4-20mA reading circuit. We verified our circuit using a 4-20 mA generator and confirmed the issue lies with the torque sensor's 4-20mA output.

We have a bearing supporting the shaft being measured. I am trying to gauge the size and shape the mount the torque sensor will be affixed to (thus the reactionary forces the support mount will be subject  to).
Due to the nature of the system, it will be mounted about 1 meter up from the ground. Will this installation work properly?

I want to build a machine to test bits as per attached.
I would like to see the amount of torque from the drill and be able to set a given torque resistance, my drill would cycle on and off. Let me know what of your products I would need, I would like to be able to output the data to a computer.

Hello,

I am interested in purchasing the 500nm version of this but would like to understand its capabilities a little more.

Does the sensor provide feedback allowing adjustment in RPMs to take readings from free speed down to stall?  From what I see it appears to just output current speed, torque and RPM, is this correct? I would like to collect the data and be able to graph it to analyze torque and power vs. RPM curves.

I am working with a 200 ftlb air ratchet for industrial applications and need to understand the power output at various RPMs.

1. I want to check the torque of my product within the range of 1-9 Nm (Spec range). I plan to attach it to a jig socket, insert my product, and manually rotate it by hand through a 360-degree angle. Can this sensor provide and transmit the average torque data as a single value after rotating it 360 degrees?

2. Which option should I select based on the application described above?

3. Do you have any authorized dealers in Malaysia?

We have a torque sensor from ATO with the software.
We have some questions regarding the ATO software 200 torque reading from the torque sensor

Question 1
It indicates a transfer rate of 500 readings per second at 38400 bps. However, in Excel, the software seems to send approximately 200 readings per second. The question arises: is there a relationship between the time and the torque/RPM data transmitted by the torque sensor? Essentially, are the readings (1 to 217) as per Excel sheet from the torque sensor progressively increasing over time?

Question 2
We have inquiries about the correlation between RPM and torque sensor, as in our data, there are instances where RPM is rising while torque lacks any recorded readings.

How can I connect 2 sensors at the same time, I need to see the parameters for the input sensor and the output sensor. It seems that only one sensor can be connected, but I need 2 at the same time, to have a clear comparison.

I'm interested in purchasing the rotary torque sensor

I have two questions:
1) Is the calibration certificate NIST-traceable?
2) Can you point me to a description of how the associated software works? I'm assuming I can access the Serial Port data with or without the associated software right?

For our case, it won’t be practical to access the sensor and reset manually in every power cycle. So, is it OK if commanded by the PLC after each power ON through RS485 channel? We expect a high stability of sensor as the device we designed is intended to use for the high accuracy measurements.

We noted in the sensor that the ZERO value is shifting automatically after few minutes of power up. What could be the reason? The shifting is around  /- 0.03 Nm
Is it normal and within the sensor stability capabilities.  What is the best way to overcome the zero offset shifting issue?

I am interested to know about the digital torque sensor (Capacity: 100Nm, Output signal: 4-20mA).
Can this particular model read torque less than 10 Nm?
Will the sensor provide torque values even at low speeds (input shaft rotated by hand)?
Can the sensor take axial loads, and is there a possibility that the axial load might affect the torque measurement?
If the product does not work as needed, can it be returned?
Regards,

I would like to buy a torque sensor (maximum torque larger than 1kNm, maximum speed higher than 3000rpm) for our motor testing platform.  Could you please send me a quote with detailed descriptions? Thank you very much!

Default value when we received the unit, it was 2 for a display range of  /-50.00N.m. If I changed this value to 3, the range on the display change to  /-5.000N.m? Is this correct?

This powder brake can get out of alignment over time (or with certain use cases)? If so, we do we need to do exactly? Tap is with a rubber hammer to redistribute the powder?
And I understand that it’s critical to stay under the rated current. Any other advice?

Please could you be more specific?
I have Panasonic plc and do I only need to see two data in the plc through rs485?
For example, I want to see RPM and Torque. With the plc, I will send the data to an HMI and I will be able to graph that data. Please help me.

Hello, I am trying to communicate the torque sensor to a PLC through RS485, but I cannot communicate.
It is a Panasonic FP0R plc. What are the addresses in decimal to place in the plc so that it can read torque and rpm?
In the manual, I cannot clearly understand how the data is to be read and written from the sensor to the PLC.
Thank you very much in advance, and I look forward to your prompt response.

Good afternoon!
We have the digital rotary torque sensor ATO-TQS-D03 (DYN-200) .
Now it doesn't measure torque. It's writes "error" or "error4".
What do these errors mean?

Thank you for the help!
We are trying to use this torque sensor to read  2.5Nm and -2.5Nm.
Would the 5 Nm capacity with ±5V be the device we should be looking to use?
If so, could you please provide a quote?

Hello, I am trying to communicate the torque sensor to a plc through RS485, I cannot communicate, it is a panasonic FP0R plc, what are the addresses in decimal to place in the plc so that it can read torque and rpm, in the manual I cannot clearly understand how the data to be read and written from the sensor to the plc is routed, thank you very much in advance, I look forward to your prompt response.

I have a torque sensor DYN-200 0-500Nm.
We tried to check the correctness of the sensor torque using a torque wrench of 35 Nm and it read the sensor torque of 324 Nm with setting dec. This point, why not the same?

Is there any standard calibration done on the sensors or could calibration be done?

I'm looking for a pair of torque sensors that can measure shaft torque on either side of a gearbox, running in both directions.
Our configuration is motor - torque sensor - gearbox - torque sensor - load.
On the high torque side we will have a maximum torque between 240 and 310 Nm (we have flexibility in the system design right now to allow for that range of maximum torques) and on the low torque side, we have a maximum of torque of 100 Nm with a maximum angular speed of 165rpm.
We were initially considering rotary torque sensors for both sides, however, we are budget conscious and so we also wanted to consider using a torque reaction sensor on the motor side.  
How do the two compare in performance, would having a torque reaction sensor connected between the motor stator and the frame the motor is mounted on seem like a suitable application for such a sensor?
I also wanted to discuss accuracy and reliability, looking at the prices on your website your products are significantly less expensive than competitors I just wanted to discuss that, and any impact the low cost may have on your sensor's accuracy and/or reliability.
If you believe that you have any products that are suitable, can you please provide us with budgetary and lead time estimates to Toronto, Canada?
Lead time is important to us and we likely can only accept a maximum lead time of 4 to 5 weeks due to project constraints.
We intend to use a Labjack T7 Pro to read an analog voltage as the torque transducer output, if possible.

When I read the user manual for the unit, we need to install the bearing between the drive and shaft of the load cell and a bearing between the load shaft.
Is it possible to be coupled directly on the shaft of the load cell without using the bearing?

Thanks for the info.  
A couple more questions:  
We ordered the meter with the 4-20 mA output
(and the label on the meter box lists a range of 100 N.M.).  
Is the 4-20 mA output scaled to correspond to 0 -100 N.M.?  
Also, is the 4-20 mA output loop powered (need to provide power for the 4-20 mA loop) or self-powered (only need to measure 4-20 mA from the meter)?

Hello! I purchased one ATO-TQS-DYN-200 sensor and I want to interface it to my custom-made PCB, via a MAX485 transceiver: on one side I connect the signals A and B coming from the sensor, on the other side I will connect the Rx, Tx and DE/RE to my PCB, so that I will be able to read the measurements of the the sensor using Modbus RTU protocol. During my implementation, I am noticing that when the signal DE/RE is low, the signals A and B are very noisy and this causes problems in the reading of the reply coming form the TQS-DYN-200. I can see this noise using a logic analyser.
Could you help me solving the issue?

I want to ask some questions about the torque sensor:
1. Is the RS485 output signal using Modbus RTU protocol?
2. Can your software work with other sensors from other companies via RS485?

I have purchased the a rotary torque sensor presented in the link https://www.ato.com/rotary-torque-sensor-10000-nm#quickTab-reviews for 0.1Nm maximum torque like 2 years ago.
I didn't use it since then, now when I'm using it the shaft looks to be heavy for a 0.0001Nm resolution and a major portion of the torque is lost due to the torque sensor friction.
Is there a way to decrease the sensor friction (by lubrication or something) and how?
And is it normal for the shaft to be that heavy?
Note: I can provide a video showing how heavy is the sensor rotation.

Currently I am in Hobart Indiana to finalize our FAI preparations. I have one questions though on how to calibrate the sensor. I am particular looking for the “coefficient” mentioned in your user manual on page 3. Where can I find this value on interface 1?
It probably has a different name as no “coefficient” is mentioned. Can you assist?
If possible, please send screenshots to easy resolve.    
Thanks.

Thanks a lot for your response and quotation.
Meanwhile we created a tolerance calculation sheet, which is attached as excel file.
We need to understand if your product is capable to measure our stepper motor from 2 Nm to approximate 20 Nm.
May you check this calculation sheet with your tech team, if it is correct?

I have very similar question about reading out the speed sensor of my DYN-200 using digital counter. I didn't realize that the OC was the default option and I actually need TTL. How can I convert the signal so that my TTL device can read it out?

For the output speed of this sensor, the specifications state the ''OC'' output is standard configuration, and 5V TTL output is optional.  
Does ''OC'' mean open collector?  Also, how does the 5V TTL output option get implemented?  
Is it a different part? Thanks.

I am writing to ask 2 questions regarding the ATO-TQS-D03 and the DAQ software provided by ATO.
We have been conducting some torque measurements on a system and I had a question regarding the torque sensor displayed numerical values on the LCD display versus the recorded numerical values in the DAQ software. I noticed that both the RPM and torque measurements in the DAQ software are recorded as 10x larger than the displayed and as far as I can tell true values.
I have reviewed all the DAQ software settings and I cannot clearly find a parameter that would allow me to adjust the DAQ recorded value to the true value which is 10x lower. Is there a way to change this setting in the DAQ software so that I don't have to adjust the numerical values after I export them? Is there a setting that I can adjust on the torque sensor itself in the parameter settings that may be able to modify the values to the true value when being sent to the DAQ software?
My second question is about some of the measurements that we have been getting on the system we are testing. I have provided three pictures, one of the simplified system and a screenshot of the torque measurements. My supervisor is curious if, given the system we are testing, in your experience do the oscillations in the measurements appear generally correct to you? With respect to the values in this plot, I actually divided the raw RPM and torque values by 10 to get the graphed values which are the same as the displayed values on the LCD and what seem to be more theoretically correct to the values we were anticipating.
I provided a third picture of the torque measurements of a radial bearing supported screw that I conducted some torque measurements on and we were wondering if you might be able to shed some light on why the values are oscillating so regularly, we have some ideas but the team wanted me to reach out to the experts to hear what you thought.
The torque and RPM are different in each graph but the legend is at the bottom of each picture. Any help would be greatly appreciated!
Just for reference we are using the ATO-TQS-D03 with 5N-m capacity,  /-5V output and we are purchased the USB to RS485 cable pus software that is supplied by ATO.

To make sure, I would like to ask again whether we are both talking about 30 times gravity and not about grams. Can you please confirm that again?

We would like to use the digital rotary torque sensor in one of our experiments with the axis vertical. Can you tell us if it can withstand a momentary load of 30G in this position?

I'm interested in using your torque sensor in a test jig we are building to cycle test a hinge. We would like to actuate the hinge (both clockwise and anticlockwise) at approximately 0.1 to 1 rpm over the range of about 180 degrees, and measure a peak torque between 2-3 N.m in both directions. We are intending to characterise the average and peak torque that the hinge requires over a large number of cycles.

In particular, I was looking at the 5 N.m model with the RS485    /- 5V option - would this work for our application ? Is the 5V output directly from an amplifier (ie analog) as opposed to generated by a DAC?

Do you provide the connector/cable ? We do not need the USB version of the cable or the software, as we have a custom system it will be integrated with (RS485 is already present)

Could you please also tell me if you have any information on the number of cycles / the lifetime of the device?

I’m currently working on equipment for capping operations and am looking to implement a sensor that can provide readings for torque and RPM of a main shaft. I saw that ATO offers digital rotary torque sensors (https://www.ato.com/rotary-torque-sensor-10000-nm) and had a few questions regarding the device.

Can this equipment output PEAK readings of torque? One of the key metrics for my equipment will be maximum torque applied before the operation ends
Can this device be mounted so that the shaft is vertical? Could the red housing be left hanging free in the air or will it have to be mounted to some supporting fixturing?
Do the torque sensors only come in these keyed shaft configurations?

Please let me know if you are able to answer these questions!

We use multiple 100 Nm sensors and we are quite content with them.

My question is, can we operate these sensors in colder temperatures than -10℃,  i.e. will they be operational in -50℃ with an error?

What is the IP classification?

I need a range of 0-50 Nm and 0-1200 rpm that can send a signal 0-5V or 0-10V to a data logger. Also needed will be necessary shaft couplers to go from the transducer to 25mm shafts. Any assistance in selecting the correct equipment is appreciated.

Is this Digital Rotary Torque Sensor achievable for my application that requires 4 torque transmitters to be mounted on the shaft between the gear drive and the equipment. 4-20mA output is required. This is also in Class 1 Div 2 group C/D.

I apologize in advance. I am not at all in the field of testing rotary systems. I am interested in purchasing a digital rotary torque transducer. What I am asking is what reference load is recommended at the other end of the device. I would like to connect a small DC motor at one end and measure its torque/rotation per minute for a given voltage input. Does the other end of the sensor have a rotating disk of known weight and moment of inertia as a reference?

What wires do I connect to the breakout board to read the torque with a serial converter?

What is the signal output type for RPM. Does this output in Quadrature?

May I ask for a clarification on the maximum rotating angle specification? "2.60*10rad (0.149°)". Can this sensor be used for multiple rotations?

2.6 * 10 rad = 26 rad = 1490 deg
What does the 0.149° value reprepsent?

We are using a 4-20mA output sensor, and we want to read torque in both directions. It seems the 4-20mA only supplies the absolute value. Is there a way that we can set the 0Nm at 12mA and get both positive and negative readings around that point?

I am integrating the torque sensor ATO-TQS-D03 in a design.
Per my calculations, the torque value to be measured could go up to almost 100Nm (93).
What happens if we exceed this value due to the starting torque of the driving system?
Do we just get bad reading, or is there a risk of mechanical or electrical damage?

For the 100 Nm model, Which holes are for mounting and anti-rotation?
Can 4 M8 depth 10 be used for mouting?

My name is Erlantz Otaola and I write on behalf of added value solutions, a company devoted to developing mechantronic equipment for big science and space. Currently, we are looking for a torque meter for a bench we are developing. This torque meter should measure up to 300 mNm with a minimum resolution of 0.1mNm. Looking at your page, we have come across the digital rotary torque sensor, which seems to fit our purpose. However, we would very much appreciate your assessment of this. Besides, we would like to know the price and lead time for the digital rotary torque sensor or any other you consider that fits our application better.

Will our ATO-TQS-D03 torque sensor be able to measure up to 300 mNm with a minimum resolution of 0.1mNm? If yes, then what is the measuring range?

SKU: ATO-TQS-D03, your 100Nm will measure how low?

For your ATO-TQS-D03 digital rotary torque sensor, is this a contactless design or with slip rings?

SKU: ATO-TQS-D03
what is the zero torque output voltage of the 0-10V option?
I want to get negative torque in case of reversing direction, do I need to use  /-5V output?

Can your torque sensor be setup such that one end is connected to the motor while the other end is connected to nothing? What sort of reading will I get if this is the case?
