adopts the imported touch screen for data input and data display. The original American imported force sensor is used as the pressure acquisition signal. The system can calculate the pressure signal and displacement signal at the speed of 500 times per second, sound various alarms and draw the curve. The is mainly applied to the combination of piston and piston pin of gasoline engine, press-in of interference fit between bearing and shaft sleeve, press-in of motor rotor and rotating shaft, water pump, turbocharger, gearbox, gear and the interference fit in the automobile industry and the motor industry. It is a piece of pressing detection equipment with high-performance, high-precision and high efficiency.
