DET series LVDT sensor (displacement position sensor) is a common sensor for measuring linear displacement. Because of its simple structure, high accuracy and strong reliability, it is widely used in various fields. The displacement sensor has many functions, but at the same time, there are many reasons for the failure of the displacement sensor.

Fault reason of DET series displacement sensor

There may be many reasons for the failure of the LVDT sensor. For different types of displacement sensors, their failure reasons may also be different. Therefore, when using and maintaining the displacement sensor, relevant regulations and guidelines should be followed to ensure its normal operation and effectiveness.
The most common cause is wear or aging. Because displacement sensors usually need to withstand harsh working environments such as high temperature, high pressure, vibration and repeated load, long-term use may lead to wear or aging of internal components of the sensor, thus reducing its measurement accuracy and stability; External damage is also a major cause. Because displacement sensors are usually exposed to the working environment of machinery and equipment, they may be affected by physical impact, impact, pressure and other external factors, resulting in damage or failure of internal components of the sensor; Improper cleaning can also cause machine failure. Because the displacement sensor needs to maintain a dry, clean and dust-free environment, if improper cleaning solution or cleaning method is used during cleaning or maintenance, the sensor element may be damaged or invalid; Because the displacement sensor usually requires external power supply, if the power supply is unstable or the power supply fails, the sensor measurement signal may be abnormal or invalid; The displacement sensor needs to be installed in a suitable location and environment. If the installation location is incorrect or disturbed by the environment, the measurement accuracy and stability of the sensor may be reduced.
In short, when the DET series displacement sensor encounters a fault, it should be diagnosed and repaired according to the specific situation to ensure the normal operation of the sensor.

Judge the quality of DET series displacement sensor

In order to ensure that the LVDT displacement sensor can work with high intensity and accuracy for a long time, we should learn how to judge the quality of the displacement sensor when selecting the displacement sensor.
The first thing to pay attention to is the accuracy of the LVDT displacement sensor, which is a very key indicator of the displacement sensor. Generally speaking, the higher the accuracy, the more accurate the data measured by the sensor. Therefore, it is necessary to pay special attention to the accuracy index of the sensor when purchasing the sensor to ensure that it can meet the actual needs.
The DET series sensor needs to maintain high stability during use to ensure the consistency and reliability of the sensor measurement results. Therefore, it is necessary to check the service life, anti-interference ability and other indicators of the sensor to evaluate whether its stability meets the requirements.
In some cases, the sensor is required to have a high response speed, which is also one of the important indicators to evaluate the quality of the sensor. The faster response speed is, the better the real-time performance of the sensor will show.
Some industrial environments are relatively harsh, requiring sensors with high durability to cope with harsh working conditions. When selecting and purchasing sensors, we need to pay attention to the sensor’s material, protection grade and other indicators to ensure that the sensor has sufficient durability.
To ensure the quality and after-sales service of the sensor, we need to select well-known LVDT position sensor. Select the appropriate LVDT displacement sensor according to the actual budget, and do not blindly pursue low prices, otherwise the accuracy and stability of measurement may be affected.
Finally, reliability is an important index to judge the quality of DET series displacement sensor. The sensor needs to have good reliability in the process of use to ensure the accuracy and reliability of the measurement results. Special attention should be paid to factors such as the brand of the sensor and the reputation of the manufacturer to ensure the reliability of the sensor.
