When the tensile testing machine does the test, it will encounter different situations. Today we will explain one of the situations - how to fix the displacement problem when the tensile testing machine does the test? Simply can be divided into the following three steps:
>>1. Check the displacement sensor: >
>>If there is a problem with the displacement, the displacement sensor should be considered first, as the tensile testing machine system is a closed loop system, if you want to know which part has the problem, it is necessary to break the loop in the system and make it an open loop system. In this way, it can be assessed whether the sensor signal from the tensile testing machine is correct. At this time, the response signal of the displacement sensor should also be disconnected to make it an opento make a loop. At this time, the workstation will receive a signal from the controller to measure the information sent back by the sensor. After several repetitions, the sensor's response data value can form a straight line that changes linearly, so it can be clearly seen that the sensor has no problem is more.
>>2. Check the Amplifier Unit:>
>> After the displacement sensor error has been resolved, due to the closed loop nature of the tensile testing machine, it is also necessary to check the amplifier unit for normal condition by disconnecting the input signal from the amplifier unit. Remove the input wiring, add DC output signal to the amplifier unit, and then measure the input state of the tensile testing machine amplifier unit. After several repeated experiments, you can get the linearChange trend data of the input signal is obtained from the Amplifier Unit to let you know if there is a problem with the Amplifier Unit.
>3. Check the tensile testing machine parameter setting: >
>> The stroke of the actuator in the tensile testing machine hardware under normal conditions should be ± be 50 mm. If it does not match this value, there is a problem with the system settings parameters. The system parameters need to be reset. If the reading on the tensile testing machine is still not correct, it can be concluded that such a problem can only be rectified by resetting the position measuring system.
