NJY-104 torque controller

The NJY-104 speed controller is combined with a non-contact torque sensor to solve real-time torque testing. It has the advantages of high accuracy, fast frequency response, good reliability, and long service life. Widely used in the research, design, manufacturing, and maintenance industries of various power machinery and its transmission machinery. Used for detecting load torque and input power of equipment such as electric motors, fans, pumps, reducers, winches, drilling machinery, etc. In terms of design, real-time level detection of input channel signals is adopted in hardware, and the input channel is electrically isolated from the main control part by using off coupling. Watchdog technology is used to improve the system's anti-interference ability. By using digital filtering technology in the software, the measurement results are more accurate.

  • After-sales

    1. LONGLV provides customers with installation and debugging services, as well as other technical consultations. If necessary, technical personnel can provide on-site technical training. If the customer has any technical questions, the technical personnel will provide a response within 4 hours.
    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.
    If an objection is raised within the deadline and it is confirmed by both parties that it is a product quality issue or production has not been carried out according to the requirements confirmed by both parties, it can be exchanged or refunded. If there are no quality issues and the shipping model andthe contract signed model are complete and correct, no return or exchange service will be provided.
    4. The products returned for repair will have a test result issued within 3 working days and the repair will be completed within 7 working days.
