High-precision ESMSNJ07 flange static torque sensor for Alloy steel material
Working Principle
ESMSNJ07 static torque sensor operates based on the principle of resistive strain. When torque is applied to the sensor, the elastomer inside deforms, and the strain gauges attached to the elastomer change their resistance accordingly. The bridge circuit composed of the strain gauges outputs a voltage signal proportional to the torque due to the change in resistance. This signal, after amplification, filtering, and conversion, becomes readable torque data.
Product Features
- High measurement stability

application scenarios
1. Motor and Gearbox Testing:
Measure the motor's stall torque.
Test the gearbox's transmission efficiency, backlash, and starting torque.
2. Valve Actuator Testing:
Monitor the opening/closing torque of electric/pneumatic valves to prevent valve jamming or seal surface damage.
Used for valve torque calibration stands.
3. Fastener and Tool Calibration:
Calibration and verification of torque wrenches and electric screwdrivers.
Monitoring of bolt tightening processes (static final torque confirmation).
4. Material Mechanics Testing:
Torsion testing machines for materials, testing the material's torsional strength and shear modulus.
5. Robot Joint Testing:
Measure the output torque of robot joints in a static holding state.
6. Wind Power Generation:
Static torque monitoring of pitch systems and yaw systems.
