The movement of objects is very common in real life. Usually we do not pay attention to the amount of object movement, but it is necessary to know the amount of change in the relevant industries, water conservancy or liquid level measurement control. Scientific measurement of displacement changes using displacement sensors.

The so-called displacement sensor is a system device, and the device displacement sensor as a measurement plays a key role in many applications. It is used to measure the mechanical displacement of the instrument, and the amount of displacement of the machine during industrial process changes. Displacement sensors according to the signal output can be divided into analog displacement sensors and digital displacement sensors. Usually we see resistance type capacitive and inductive eddy current type and so on are analog displacement sensors, they have a unified feature is simple in structure. Compared with digital displacement sensors, the measured displacement change output is converted into digital readout directly. Compared with analog displacement sensors, it is more complicated, but its advantage is that the measurement accuracy is relatively high, and it is more accurate enough. Read the measured displacement change.

Displacement sensors have high accuracy requirements in terms of detection, such as constant requirements for ambient temperature, precise control requirements for motion mechanisms, and so on. At present, in order to detect the installation problem of the sensor during displacement, the developers have developed a laser displacement sensor that uses the principle of echo analysis to measure the distance to achieve a certain degree of accuracy. The interior of the sensor is composed of a processor unit, an echo processing unit, a laser transmitter, and a laser receiver. At present, in the displacement sensor production industry, the displacement detection distance is the most popular topic. Perhaps the measurement displacement is not the ultimate goal, and a series of problems such as the magnitude of the displacement change and the required measurement accuracy are all corresponding to what kind of application.

Displacement sensor buyers need to understand the working principle of the displacement sensor and the installation method of the displacement sensor, so as to know how to choose. The displacement sensor is similar to other sensors in that it finally converts the amount of change seen in reality into an electrical signal. Generally, according to the size of the displacement change and the accuracy required by the user, he decides which sensor to use, considers its error, and considers whether its travel distance corresponds to whether the user's application environment affects the data collection. The same displacement sensor is a sensitive device, and it is necessary to pay attention to the use of the precautions at the time of purchase, so that the sensor has a longer life.
