Overview
User Manual

LVDT (Linear Variable Differential Transformer) sensor can directly change the amount of mechanical changes into a standard electrical signal for computer data acquisition or PLC process control. It is a powerful tool to detect and analyze the displacement, distance, elongation, movement, thickness, vibration, expansion, liquid level, compression, strain and other physical quantities. LVDT displacement sensor can be not only used with the instruments, but also used alone.

Applications: LVDT sensors are widely used in aviation, electric power, petrochemical industry, machinery, military, textile, automobile, coal industry, seismologic surveillance, universities, research institutes and other fields.

Precision at its Best

The LVDT Sensor has truly impressed me with its precision and accuracy. I rely on this sensor for critical measurements in my industrial applications, and it has never let me down. Its ability to provide consistent and reliable measurements, even in challenging environments, is remarkable. The build quality is top-notch, and it's evident that this sensor is designed for durability.

Problems in sensor use

I need assistance in using the 50 mm sensor with a signal conditioner. When calibrating the indicating lights do not change when prong is pushed.

1. Please connect the sensor to the power, find the scale point (black marking line), and start to push the sensor's telescopic shaft. Please use a multimeter to measure whether the current changes in the range of 4-20mA. The sensor has a zero position and a black mark line. When the sensor rod is pushed to this position, it should be around 4mA, and then continue to push inward, that is, it will slowly change from 4mA to 20mA.
2. Wiring method: directly connect the red wire of our sensor to the positive pole of 24V, the black wire to the negative pole of 24V, then connect the yellow wire to the mA gear of the multimeter, and connect the common terminal of the multimeter to the negative pole of 24V.
3. The indicator light does not change, what is your plug indicator light for? We can just visually observe the sensor current, because the output is 4-20mA, if the current of the multimeter changes to 4-20mA when the sensor is pushed, then there is no problem with the sensor. Otherwise, it is not our sensor problem.

Please guide me.

We have purchased ATO-800 along with tension and compression load cell and R485. We could successfully run the DAQ system software to read the values from the load cell.
Now, I am interested plugging in an LVDT with my experimental setup and want to read the displacement values using ATO-800 and DAQ system. I already have a 2 inch LVDT which fits well with the experimental design. Please guide me if I can somehow use some other software to read displacement values using ATO-800 too because it allows me to take readings in milliseconds. Or if there is something else I can do about it. The readout logger, I currently have allows me to go as low as 1 second only.

This ATO-800 is usually used to measure load cells, and it can only receive MV signal. If the output signal of your LVDT sensor is MV, it can be used, otherwise it can't. May I ask what signal your LVDT sensor outputs?

LVDT sensor meets my needs

This LVDT sensor purchased from the ATO.com online store satisfies my needs very well. I am a physics enthusiast and have a strong interest in physics. This LVDT sensor can detect and analyze various physical quantities. I like to use it to study physics. This is my most satisfying shopping.
