Torque wrench calibration machine

        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 calibration machine can be equipped with automatic control system to realize automatic loading.

Standards
    1、ISO 6789
    2、EN 26789
    3、JJG 797-2013
    4、JJG 707-2014

Features and Advantages
    1、Top and the most authoritative metrological institution (NIM) in China participates in research and development.
    2、High accuracy and wide range：The system accuracy is 0.3%; Range covers 1Nm~3000Nm (Extended ranges can be customized)
    3、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 wrench testing more reliable.
    4、Convenient and efficient：When the torque wrench is placed on the long thrust arm, the wrench can be quickly placed in a horizontal state through the height adjustment mechanism. After the horizontal position of the wrench is adjusted at the force action point, the slider movement mechanism on it's skateboard quickly moves to the position of the wrench thrust point. 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.
    5、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.
    6、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.

        500 N·m and below ranges, such as TWC-50, TWC-100, TWC-200, TWC-500 can be brought to the field. It can also be equipped with a large range or small range sensor to extend the range up or down.

Specification

Model	Accuracy	Range	Loading mode
TWC-100	0.3%	(1-10)N·m/(10-100)N·m	Manual
TWC-200	0.3%	(2-20)N·m/(20-200)N·m	Manual
TWC-500	0.3%	(5-50)N·m/(50-500)N·m	Manual
TWC-1000	0.3%	(10-100)N·m/(100-1000)N·m	Manual/Automatical
TWC-2000	0.3%	(20-200)N·m/(200-2000)N·m	Manual/Automatical
TWC-3000	0.3%	(30-300)N·m/(300-3000)N·m	Manual/Automatical
Remark：Each model can be equipped with additional sensors as needed. Larger range torque wrench calibrator can be customized.

Calibration software
    1. Presetting, data recording, automatic determination of whether the data is qualified, printing and output, calibration and adjustment, etc.
    2. Pictorialize the loading process. It's easy to choose operation mode (Trace mode, peak mode), unit (N·m、in.lb、ft.lb、kgf·m etc.), Parameter setting (loading mode selection, loading parameter selection, etc.)
    3. Two languages version (Chinese and English)

After-sales service system
    1、ISO 9001 quality management system certification.
    2、Maintenance laboratory with sensors and torque testing.
    3、CNAS calibration laboratory with sensors and torque testing.
    4、The sensor replacement is convenient and fast. The instrument only needs to mail the sensor and display instrument during the subsequent verification and calibration.
