What are the two types of torque sensors?

(Summary description)Torque Sensor - Non-contact torque sensor input shaft and output shaft are connected by torsion bar, the input shaft has splines, and the output shaft has a keyway. If the torsion bar is twisted by the turning moment of the steering wheel, the relative position between the spline on the input shaft and the keyway on the output shaft will change. The relative displacement change of the spline and the keyway is equal to the twist of the torsion bar. Therefore, the magnetic induction intensity of the spline changes, and the magnetic induction intensity changes, which is converted into a voltage signal through the coil. The non-contact torque sensor adopts the non-contact working method, which has long service life, high reliability, not easy to wear, small delay, small influence of shaft deflection and axial offset, and has been widely used in the automotive field.

Torque Sensor - Non-contact torque sensor input shaft and output shaft are connected by torsion bar, the input shaft has splines, and the output shaft has a keyway. If the torsion bar is twisted by the turning moment of the steering wheel, the relative position between the spline on the input shaft and the keyway on the output shaft will change. The relative displacement change of the spline and the keyway is equal to the twist of the torsion bar. Therefore, the magnetic induction intensity of the spline changes, and the magnetic induction intensity changes, which is converted into a voltage signal through the coil. The non-contact torque sensor adopts the non-contact working method, which has long service life, high reliability, not easy to wear, small delay, small influence of shaft deflection and axial offset, and has been widely used in the automotive field.

Torque Sensor - Strain Gage Sensor Torque measurement uses strain gage technology. Attach the strain gauge to the elastic shaft to form a measurement bridge. When the elastic shaft is slightly deformed by the torque, the bridge resistance value changes, and the change of the strain bridge resistance is converted into the change of the electrical signal to realize the torque measurement. The sensor completes the following information conversion: the sensor is composed of an elastic shaft, a measuring bridge, an amplifier for the instrument, and an interface circuit.

Torque Sensor - High-performance wireless torque sensor combines sensors with wireless communication technology to realize wireless transmission of data. The electric torque signal is amplified by the signal processing circuit controlled by the single-chip microcomputer, and the digital quantity code collected by the encoder after A/D conversion is sent to the sending module for transmission. When the receiving module receives the data, the decoder passes the translated data to the single disk as the torque data value indicated by the LED. The sensor data acquisition and transmission circuit is composed of torque sensor, signal processing part, single chip microcomputer and wireless transmission circuit. The torque sensor sends the deformed electrical signal generated by the resistance variation to the signal processing circuit. The signal processing part amplifies the sensor analog signal extraction, and performs mode/digital conversion. The microprocessor controls the work of each part of the system and processes digital signals. Under the control of the microprocessor, the wireless transmitting circuit appropriately encodes and processes the information data collected by the encoder, and transmits it to the transmitting module. Realize wireless transmission.

What is an electronic torque sensor?

The Electronic Torque Meter is a portable high-performance axial power measurement instrument used for fan, pump experiments and field energy efficiency evaluations. The electronic torque meter creatively abandons the cumbersome and complicated installation process of traditional mechanical torque sensors, which is difficult to achieve in many field environments, realizes real-time measurement of fan and pump motor efficiency, and monitors the working status of each part of the fan and pump motor during use. , providing real-time, real and reliable data for studying the usage status of fans and pump motors. Avoid the influence of the improper installation of the electrical torque sensor on the experimental results.

The electronic torque meter can completely replace the axial power measurement function of the traditional torque sensor, and can obtain the real-time efficiency of the fan and pump motor, providing a strict and scientific evaluation method for the energy saving of the fan and pump device.
