Electronic tensile testing machine is a mechanical testing machine for static load, tension, compression, bending, shearing, peeling and other mechanical property tests of various materials. It is suitable for various physical and mechanical property tests of plastic plate, pipe, profile, plastic film, rubber, wire and cable and other materials. It is used for material development, physical property test, teaching and research Quality control and other indispensable testing equipment.

Optimization of sensor and measurement and control system of electronic tensile testing machine:

The quality of the force value sensor of the electronic tensile testing machine determines the accuracy and force measuring stability of the testing machine. At present, the sensors for tensile machines in the market generally use S-type sensors for small force values, spokes sensors for large force values, and resistance strain gauges are generally used inside the sensors, If the accuracy of strain gauge is not high or the aging resistance of the strain gage is not good, or the material of the sensor is not good, the precision and service life of the sensor will be affected. The imported sensor has high precision, good linearity and very stable performance, which will not change for decades.

At present, the measurement and control system of most tensile testing machines in the market adopts 8-bit single chip microcomputer control, with low sampling rate and poor anti-interference ability. In addition, it is AD converter. If the number of bits of AD converter is low, that is, the resolution is low. Then the measurement will not be accurate. The measurement and control system adopts the controller developed by advanced 32-bit ARM technology to make the program run more smoothly and the system more stable. The sampling rate can reach 200 times per second. Coupled with 24 bit high-precision low noise high-speed AD converter, the whole measurement and control system can control the whole test process with higher precision and stability, so that the whole test process can achieve constant force control, constant displacement control, constant deformation control, low-frequency fatigue control, and arbitrary program control.
