  Yuxi Torque Wrench Calibrator is developed and manufactured by Shandong Yuxi instruments co., Ltd. in cooperation with National Institute of Metrology, China (NIM, Top metrological scientific research center and national legal metrological technical institution in China). It can be used to calibrate various torque wrench and tightening metering devices.

Torque wrench calibrator consists of frame, loading mechanism, high precision torque sensor and display instrument. Multi-sensor combination can be used on the same frame and mechanism

The STM series is manual loading, and the DSTM series is equipped with automatic control system to realize automatic loading.

 Application

Torque wrench calibrator is a system that is used for torque testing, calibration and verification in the industrial field. It can test and calibrate most torque wrenches, torque screwdrivers, multiplier and non-impact pneumatic power tools etc.

Standards

   ISO 6789,EN 26789, JJG 797-2013, JJG 707-2014

Features and Advantages

• Top and the most authoritative metrological institution (NIM) in China participates in research and development.
• System traceability: This system provides the calibration certificate of National Institute of Metrology, China (Option)
• High accuracy and wide range：

The system accuracy is 0.3%; 

Range covers 1Nm~3000Nm (Extended ranges can be customized)

• Good stability:

    Sensor rotation, different from the common pushing wrench arm form. The force bearing point position remains unchanged during loading, which ensures the stability of torque measurement and spanner testing more reliable.

• Convenient and efficient：

     Loading test bench can load automatically and semi-automatically on request. It can measure the torque clockwise and counter-clockwise.

     The same loading mechanism can be used for multiple ranges by replacing sensor.

It’s easy to replace sensors in several seconds. It’s convenient for subsequent verification and calibration.

    The joint design is scientific and reasonable. It can connect tenon with different specifications.   

• Powerful function：

Users can select digital display device operation and PC operation as needed.

PC operation includes professional software, printer and accessories. This operation mode can automatically accomplish data collection, processing, storage, search and certificate printing etc.

• Wide application:

It can calibrate preset torque wrench, pointer torque wrench, digital display torque wrench etc.

     Users can choose unit and operation mode according to wrench type.

     It applicable to Metrology institute, manufacturer and users of torque wrench.
