The RTSE Non-contact Square-Drive Rotary Torque Sensor is a high-performance sensor designed for dynamic torque and angle measurement. Integrated with an angle encoder, it provides a comprehensive solution for torque auditing and calibration applications. This advanced rotary torque sensor supports bidirectional torque measurement (both clockwise and counterclockwise) and is available in multiple rated capacities: 5Nm, 10Nm, 15Nm, 20Nm, 30Nm, 50Nm, 100Nm, and 200Nm, covering a wide range of industrial needs. The RTSE torque meter utilizes strain gauge technology combined with wireless signal transmission, allowing for non-contact data output even while the sensor is rotating. It offers standard analog outputs such as 0-5V, 0-10V, or 4-20mA for the torque channel and a pulse output for the angle channel, making it easy to integrate with data acquisition systems and industrial controllers. Each end of the sensor is equipped with a square drive interface, ensuring quick and secure attachment to torque tools or calibration systems. Its compact design, real-time feedback, and accurate performance make the RTSE torque cell ideal for torque tool calibration, fastening process monitoring, and other applications requiring rotational torque and angular position measurement under dynamic conditions.
