A load cell, also known as a load or force transducer, is a sensor that measures applied forces. Load cells are capable of measuring both tension (force required to pull something) and compression (force required to push something). In order to measure these forces, the sensor creates an electrical output that changes depending on the amount of resistance being applied.

Programmable relay stores some typical relay logic control program in internal memory in advance and realize some simple logic control and sequence control function by the user program combination and calls. The user program uses the ladder diagram or functional diagram language through panel, intuitive and easy to understand. The switching signal input by the button, switch etc.

A load cell is a force transducer. It converts a force such as tension, compression, pressure, or torque into an electrical signal that can be measured and standardized. As the force applied to the load cell increases, the electrical signal changes proportionally. We covered How to use PLC to monitor the data of load cell transmitter in our previous blog. Today we'll show you how to use HMI to display the data of load cell in real time.

A load cell is a force transducer. It converts a force such as tension, compression, pressure, or torque into an electrical signal that can be measured and standardized. As the force applied to the load cell increases, the electrical signal changes proportionally. The most common types of load cell used are strain gauges, pneumatic, and hydraulic.

In the automated production process of industries such as food and beverages, daily chemicals, medicine, semiconductors, etc., in order to ensure the consistency of product quality, the era of direct manual monitoring and intervention in the production process has gone. Liquid level measurement and monitoring are playing an increasingly important role. It can be said that the measurement and monitoring of the liquid level directly affects the quality of the product, and even whether the production process can be carried out smoothly.

A three phase converter is needed when the "phase" required does not match the "phase" available. In other words, the equipment needs three phase power and only single phase power is available. Phase converters operate by converting single phase power into three phase power. They can also provide split phase voltages from the three phase power source. A three phase converter is used to allow operation of three phase equipment when single phase electrical services are the only power available or vice versa. The majority of the time phase converters are utilized to produce three phase power from single phase power sources as utility companies will associate higher fees for three phase electrical services due to the extra transformers, cabling, and metering required. In this article, we will introduce how to convert single phase to three phase converter.

The working principle of the constant pressure water pump is as follows:

1. The VFD drives the water pump, and the pressure sensor/transmitter feeds back the pressure signal to the VFD to form a closed loop system.
2. When the water pipe pressure is less than the set value, the VFD wakes up and starts pumping water.
3. When the pressure does not reach the set target, the operating frequency will continue to increase to the rated frequency of the pump.
4. When the pressure is greater than the set pressure, the operating frequency will decrease.
5. When the pressure is greater than the sleep pressure, the frequency decreases to the sleep frequency for a period of time, and then stops pumping water.
6. When the pressure is lower than the wake-up pressure, the pump starts to run again.

We all know vertical centrifugal pumps and horizontal centrifugal pumps, both of which are centrifugal pumps. It can be used in everyone's daily life. So what is the difference between these two pumps? And what are the differences? For this issue, ATO.com will give you a brief explanation so that you can have a more detailed understanding of these two pumps.

Diaphragm pump is a new type of mechanical transportation equipment, which can be used for all kinds of corrosive liquids, liquids with particles, high viscosity, volatile, flammable and highly toxic liquids. Diaphragm pumps are divided into pneumatic diaphragm pumps and electric diaphragm pumps, and their materials are engineering plastics, aluminum alloys, stainless steel, cast iron, etc.

An electric actuator is a drive device that provides linear or rotary motion. It uses certain driving energy and works under the action of a certain control signal. Actuators use liquid, gas, electricity, or other energy sources and convert them into drive-through motors, cylinders, or other devices. The basic types are Part-Turn, Multi-Turn, and Linear.
An electric actuator is also called a valve electric device, which is the name in different industries. In the industrial pipeline valve industry, it is called a valve electric device, and in the instrument industry, it is called an electric actuator.

Soldering stations and soldering irons are common tools in soldering operations. In fact, the soldering station is also a kind of electric soldering iron. Many people call the soldering station an electric soldering iron. The soldering station is just a new welding tool that appears in the electronic welding process due to the development requirements of welding technology. Now the soldering station has developed a lot.

Limit switches are used to control the travel and limit protection of mechanical equipment. In actual production, the travel limit switch is installed in a pre-arranged position. When the module installed on the moving parts of the production machinery hits the travel switch, the contacts of the travel limit switch act to realize the switching of the circuit. Therefore, the limit switch is an electrical appliance that switches the circuit according to the travel position of the moving part, and its working principle is similar to that of a button. Limit switches are widely used in various machine tools and hoisting machinery to control their travel and perform terminal limit protection. In the control circuit of the elevator, the travel limit switch is also used to control the speed of opening and closing the car door, the limit of automatic door opening and closing, and the upper and lower limit protection of the car.

An alternator is an electrical generator that converts mechanical energy to electrical energy in the form of alternating current. For reasons of cost and simplicity, most alternators use a rotating magnetic field with a stationary armature. An alternator that uses a permanent magnet for its magnetic field is called a magneto. Alternators in power stations driven by steam turbines are called turbo-alternators.

The use of air compressors is very extensive. It can be used in instrument control and automation devices, such as tool change in machining centers.

A photoelectric sensor is a device that converts optical signals into electrical signals. Its working principle is based on the photoelectric effect. The photoelectric effect refers to the phenomenon of the corresponding electrical effect occurring when the electrons of the material absorb the energy of photons when light is irradiated on certain substances. Photoelectric switch is generally used for automation equipment. This blog mainly introduces how does a PLC control photoelectric sensor?

The proximity sensor is the general name of sensors that replace the contact detection methods such as limit switches and do not need to contact the detection object for the purpose of detection. It can detect the movement information and existence information of the object and convert them into electrical signals.

A liquid level sensor is a device used to monitor, maintain and measure the level of liquids (and sometimes solids). Once the liquid level is detected, the sensor converts sensed data into an electrical signal. The main types of liquid level sensors are ultrasonic liquid level sensors, capacitive liquid level sensors, photoelectric liquid level sensors, microwave optical sensors, etc., and their applications are as follows:

Brix refractometers are a common instrument used to measure the sugar content of a solution. Increasing sugar content leads to an increase in the refractive index. By passing light through a sample and measuring the refraction, the amount that the light bends, the sugar content can be measured.

The dew point meter is an instrument that can directly measure the dew point humidity. Place a mirror in the sample of the humid air to cool down until the moment when dew droplets (or ice crystals) appear on the mirror. The dew point meter can measure the average temperature of the mirror, which is the dew point (frost) temperature.

The working process of the main circuit of the linear DC power supply is that the input power supply is initially AC stabilized by the pre-stabilizing circuit, and then converted into a DC power supply through the isolation and rectification of the main working transformer, and then under the intelligent control of the control circuit and the single-chip microprocessor controller. The linear adjustment element is finely adjusted to output a high-precision DC voltage source. The linear DC power supply products can be widely used in scientific research, colleges and universities, laboratories, industrial and mining
enterprises, electrolysis, electroplating, charging equipment, etc.
