Torque Limiter uses proximity sensor.
Mechanical Power Transmission

Torque Limiter uses proximity sensor.

Torque Limiter disconnects main power source from down-stream components in event of torque overload or product jam. When overload occurs, proximity sensor embedded in air chamber sends signal to pneumatic, directional control valve to exhaust air from air chamber, which disconnects and protects system. Remote trip-torque setting with air regulator eliminates need for manual torque adjustments....
