Method for selecting displacement sensors

The so-calledA displacement sensor is a system device that plays a crucial role in many applications as a measuring device. It is applied to instruments for measuring mechanical displacement, as well as displacement changes in industrial processing machines. Displacement sensors can be divided into analog displacement sensors and digital displacement sensors based on signal output. The types of resistive capacitive and inductive eddy current sensors that we usually see are analog displacement sensors, which have a unified characteristic of simple structure. Compared to digital displacement sensors, which convert the measured displacement change output into digital direct reading, it is still more complex compared to analog displacement sensors. However, its advantage is that the measurement accuracy is relatively high, which is more accurate in reading the measured displacement change.

Displacement sensors have high accuracy requirements in detection, such as constant environmental temperature requirements and precise control requirements for motion mechanisms. At present, in order to solve the installation problem of sensors for detecting displacement, researchers have developed a laser displacement sensor, which uses the principle of echo analysis to measure distance to achieve a certain degree of accuracy. The sensor is composed of a processor unit, an echo processing unit, a laser transmitter, a laser receiver, and other components. At present, the detection distance of displacement is the most popular topic in the displacement sensor production industry. Perhaps measuring displacement is not the ultimate goal, and a series of issues such as the magnitude of displacement changes and the required measurement accuracy all need to be addressed in what application.

Buyers of displacement sensors need to understand the working principle and installation method of displacement sensors, in order to understand how to select the type. Displacement sensors, similar to other sensors, convert changes observed in reality into electrical signals. Generally, the selection of a sensor is determined based on the magnitude of displacement changes and the accuracy required by the user, taking into account its error, the corresponding travel distance, and whether the user's application environment has an impact on data collection. Similarly, displacement sensors are sensitive devices, and caution should be given when purchasing them to ensure a longer lifespan.
