Displacement measurement technology has been widely used in the industrial production of tension machines, testing instruments and so on. Displacement detection is the basis of mechanical quantity detection. Converting mechanical quantity to displacement measurement is one of the important components of Mechatronics technology.

The displacement detection not only provides important data for improving product quality and production safety, but also provides a basis for other parameters detection.

In tension machine, tension testing machine and universal material testing machine, the traditional static electro-hydraulic measurement and control method can not meet the requirements of the hydraulic system in performance, operation, on-line monitoring and fault diagnosis, so the development of on-line monitoring and analysis system is particularly important.

If it is found that the displacement system failures must be handled in time. If it can be solved by itself, it can be solved by itself. If it can not be handled, you can call Shanghai Jane Household Instrument Equipment Co., Ltd. for assistance. Our company has after-sales outlets all over the country. Among the problems handled by the simple households in Shanghai, there are three main causes. We will list them for you, and we will deal with them according to the situation.

1. First check the displacement sensor of the tension machine, the tension testing machine and the universal material testing machine. Because the displacement system of the tractor adopts three closed-loop control mode, the loop of the displacement system should be disconnected to make it an open-loop system. Then the feedback value of the displacement sensor is measured. After repeated several times, the feedback data of the sensor is a linear change line to determine whether the sensor is normal or not.

2. Next, check the amplifier unit. If there is no problem with the displacement sensor, the amplifier unit of the tractor should be checked. The output signal of the normal amplifier unit should change linearly.

3. If the fault is not caused by the above reasons, check whether the computer software settings are correct or re-calibrate and correct the displacement system.
