The NJL-311 dynamic torque sensor is a new product developed by our company based on specialized strain bridge technology, suitable for various torque measurement occasions that require small volume and high speed. Output 5-15kHz frequency signal or 4-20mA current signal, 0-10V constant voltage signal, suitable for long-distance transmission. This product is small in size, easy to use and install, and has strong signal anti-interference ability, making it an ideal product to replace imported torque sensors. The product is non-contact, wear free, and can reach a maximum speed of 9000 rpm, suitable for long-term high-speed rotation conditions.
