Digital torque wrench MDJJB-1000

high-precisionanti-corrosion

At present, various types of torque wrenches have been widely used in many industries, and the torque wrench calibrator is also widely used as a measuring instrument for torque wrenches. However, at present, the torque wrench calibrator still uses the method of hanging with weights and levers for verification and calibration, which makes the verification and calibration of the calibrator inconvenient. In 2013, the National Metrology Department revised the "JJG797-1992 Torque Wrench Verification Regulations". The standard torque wrench is a high-accuracy torque wrench used to transmit the value of the torque wrench calibrator. It is specified as torque wrench verification. Instrument verification equipment, currently used verification procedures are: JJG1103-2014 standard torque wrench verification procedures. 1. Appearance structure and its composition The outline structure of the standard torque wrench is shown in Figure 1 below. It consists of four parts: a torque digital display instrument, a high-precision sensor, a wrench head and a wrench rod. The high-precision sensor is installed and fixed on the wrench head and is integrated with the wrench head. High-precision sensor and torque digital display form the torque acquisition and processing part. 2. Product Features 1. Adopt microprocessor digital technology; 2. Delayed automatic shutdown and manual shutdown; 3. Anti-corrosion keys, impact resistance, good long-term stability; 4. Arbitrary alarm value setting, sound and light alarm. 5. Start zero tracking; 6. The value of the three units is automatically converted.
