ESMNJ07 Non-contact continuous measurement dynamic disk type torque sensor
Working Principle
The ESMNJ07 dynamic disc torque sensor is based on strain gauge electrical measurement technology. When torque is applied to the sensor’s elastic body, the elastic body undergoes shear deformation, causing the resistance of the strain gauges attached to it to change, which unbalances the Wheatstone bridge and produces a weak voltage signal proportional to the torque. The signal is transmitted to the measuring instrument through methods such as slip rings or wireless telemetry, and the actual torque value is obtained after conversion. Among these, wireless telemetry is more suitable for high-speed applications of dynamic disc torque sensors due to advantages such as non-contact operation and no wear.
Product Features
- High sensitivity and resolution: Able to detect minute torque changes in high-speed rotating environments, providing precise data for equipment parameter adjustments.
- Strong anti-interference capability: Features excellent shielding design, allowing stable operation in strong electromagnetic environments and ensuring the accuracy of measurement data.
- Non-contact transmission: Some adopt non-contact signal transmission methods, transmitting energy and signals via electromagnetic or optical means, avoiding mechanical friction and enhancing reliability and lifespan.
- Easy installation: Compact and lightweight, easy to install, can be mounted horizontally or vertically, with minimal requirements for installation space.
