NJL-304 Dynamic Torque Sensor

The NJL-304 dynamic torque sensor (non-contact) 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. This product outputs a frequency signal of 5-15kHz or a current signal of 4-20mA, with a voltage signal of 0-10V, 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, with a maximum speed of 8000RPM, suitable for long-term high-speed rotation conditions.

    2. LONGLV products are strictly designed and produced in accordance with the ISO9001 international quality system, with a 1-year warranty for sensor products and a 3-year warranty for instrument products, with a 7-day return and exchange policy and lifelong maintenance.
    (Human damage is not covered by the warranty, and customized products without quality issues are not returned or replaced.)
    3. For returns and exchanges caused by quality issues, Longlv will bear the return and exchange shipping costs. The cost of returns andexchanges for non quality issues will be borne by the customer.
    Note: Quality issues refer to customized parameters such as function, size, specifications, and installation method that are not customized according to customer requirements, do not meet functional requirements, have dimensional errors, and have inaccurate accuracy (excluding within the error range).
    Customized products require confirmation of drawings by both parties before processing and production. If the product does not meet customer requirements, a written objection must be raised within two weeks. If the customer does not raise an objection within the specified time limit, it will be deemed as qualified acceptance.
