Torque sensor is a precision measuring instrument for measuring various torques, speeds and mechanical powers. It has a wide range of applications and is mainly used for: 1. Detection of output torque and power of rotating power equipment such as motors, engines, internal combustion engines, etc.; 2. Detection of torque and power of fans, water pumps, gearboxes, torque wrenches; 3. Detection of torque and power in railway locomotives, automobiles, tractors, aircraft, ships, and mining machinery; 4. It can be used for torque and power detection in sewage treatment systems; 5. It can be used to manufacture viscometers; 6. It can be used in process industries and process industries.
Torque measurement: Using strain gauge electrical measurement technology, a strain bridge is formed on the elastic shaft, and the electrical signal of the elastic shaft being twisted can be measured by providing power to the strain bridge. After the strain signal is amplified, it is converted into a frequency signal proportional to the torsion through voltage/frequency conversion.
. The signal output can arbitrarily select the waveform-square wave or pulse wave.
2. High detection accuracy, good stability, and strong anti-interference.
3. No need to repeatedly adjust zero; continuous measurement of positive and negative torque.
4. It can measure both static torque and dynamic torque.
5. The small and heavy sensor can be used independently from the secondary instrument. As long as +15V, -15V (200mA) power supply is provided according to the socket pin number, it can output equal square wave or pulse wave frequency signal with impedance proportional to torque. Lightweight and easy to install.
6. Measuring range: 0-10000Nm standard optional, non-standard 20,000Nm, 30,000Nm, 50,000Nm, 80,000Nm, 100,000Nm, 150,000Nm, 200,000Nm, 500,000Nm, 1 millionNm, 2 millionNm can be customized, special range customization.
Commonly used dynamic torque sensors are mainly in the following forms: First, inductive torque sensor: This type of sensor mainly adopts a non-contact measurement method. This torque sensor has a long life, high reliability, and is not easily worn. The second is potentiometer torque sensor: This type of sensor can be divided into gear type, torsion bar type, and swing arm type according to type. Among them, the torsion bar type has a simple measurement structure and relatively high reliability, and was widely used in the early days. This type of sensor is contact-type, which is subject to wear and tear, reducing its performance. Another type is the metal resistance strain gauge type: this type of torque sensor mainly pastes strain gauges on the elastic shaft to form a measuring bridge. When the elastic shaft is subjected to torque, it will produce a slight deformation, causing the bridge resistance to change, and the change in the resistance of the strain bridge is converted into a change in the voltage signal, thereby achieving the torque measurement we want. However, this type of torque sensor is greatly affected by the strain gauge material and the accuracy of the voltage regulator.
