Steering wheel torque and angle sensor
Overview
Steering wheel torque and rotation angle sensor (also called force measuring steering wheel) is an intelligent measuring instrument with a high-speed microprocessor as the core. It is mainly used for automobile handling stability test, lateral stability test and automobile steering wheel rotation parameter measurement. The angle measurement uses a high-precision photoelectric encoder, no zero adjustment is required, and there is no limit on the number of rotations; the torque measurement uses a strain-type torque sensor. A universal aluminum alloy adapter is designed at the bottom, which can be quickly installed on the original car steering wheel.
Main features:
- With a scale display of the rotation angle, it is convenient to determine the rotation position when turning, and is convenient for test operation
- Using high-precision photoelectric rotary encoder to detect the rotation angle of the steering wheel, there is no restriction on the number of turns
- Built-in strain gauge amplifier and precise and stable excitation voltage
- Double pulse signal with anti-shake and direction identification function
- Strong versatility, compatible with mainstream steering wheels, and can be installed on the original car steering wheel with claws, without disassembling the original car steering wheel
