BRG61050 Motor Torque Sensor
Product Information
The motor torque sensor utilizes strain gauge technology and employs a toroidal transformer for non-contact power supply. It replaces the traditional toroidal transformer with a low-power signal coupler for non-contact signal transmission, effectively mitigating issues such as high-order harmonics and interference between energy and signal transformers. Additionally, it converts output spike pulses into consistent square wave signals. As a result, the torque sensor is capable of long-term, high-speed operation and has received widespread acclaim in the torque measurement industry.
1. The motor torque sensor is an integrated product of sensitive element and integrated circuit, with high precision, stable and reliable performance.
2. Output positive and reverse torque signal
3. Both ends are key connected
4. The speed can reach 1800 rpm.
