ESMSNJ03A Non-continuous Rotation Measurement Dual-Flange Static Torque Sensor
Working Principle
The ESMSNJ03A Double Flange Static Torque Sensor is based on the principle of resistive strain. When torque is applied to the sensor, the internal elastic body deforms, and the strain gauges attached to the elastic body also deform, thereby changing their resistance. The Wheatstone bridge composed of the strain gauges converts the resistance change into a voltage signal, which is then amplified, filtered, and converted by the signal processing circuit, ultimately outputting an electrical signal that has a linear relationship with the torque.
Product Features
1. Double-flange structure, easy installation
Both ends are directly connected in series with the equipment flanges, no base support required, good coaxiality, and small installation space.
2. Static measurement, high stability
Specifically designed for stationary or low-speed intermittent conditions, no slip ring leads, simple structure, long service life, and low failure rate.
3. High precision and high signal-to-noise ratio
Built-in high-precision strain gauge bridge with temperature compensation circuit, measurement accuracy can reach 0.1%–0.5% F.S, output signal is stable.
4. Strong resistance to eccentric load and bending moment
Flanges have good rigidity, insensitive to additional bending moments and lateral forces, suitable for harsh industrial installation conditions.
5. Multiple ranges and signal outputs
Ranges cover 10–5000 N·m and above, standard outputs such as 4–20mA, ±5/±10V, RS485/CAN available.
6. Suitable for harsh environments
Fully sealed housing, dustproof and moisture-proof, impact-resistant, vibration-resistant, wide temperature range -20℃ to 65℃.
7. Comprehensive safety protection mechanism
Built-in 120% safety overload capacity, features zero drift compensation and anti-interference design.
application scenarios
1. Calibration test bench for torque wrenches / tightening tools;
2. Static load torque detection for gearboxes, valves, and couplings;
3. Torque verification for assembly line bolts / nuts;
4. Material torsion testing and static torque life testing;
5. Static torque monitoring for wind power generation and construction machinery.
