Reasons for the displacement of the material torsion test machine without response or full value

Material torsion test machineAfter long-term twisting tests, various unexpected problems will occur in some parts of the equipment. Our company analyzed the reasons why the displacement of the torsion test machine does not respond and shows full value:

1) Regarding the input amplifier, if the input signal changes but there is no change in the output terminal, it is stated that the amplifier is damaged and should be replaced.

2) If there is no comparative voltage, the resistance value of the pull-up resistor is changed or there is a dummy welding, and it should be dealt with separately.

3) IfMaterial torsion test machineThe voltage at the sensor input terminal is abnormal, and the sensor's sexual orientation can be measured according to the method in "Opening and Displaying 1999".

4) If the amplifier input terminal and comparable voltage terminal of the CPU (89C52) are both normal, the CPU is damaged and should be replaced.

5) If all the above conditions are normal, check whether the output changes can be made when the sensor is moving the upper pressure plate? If there is no change, the grating will be damaged and should be replaced.
