The safety beam sensor manufacturers said that the sensor is a detection device that can sense the measured information, and can transform the sensed information into electrical signals or other required forms of information output according to certain rules to meet the transmission of information. , processing, storage, display, recording and control requirements.

Safety beam sensor manufacturers said that China's sensor industry is at a critical stage of developing from traditional to new sensors, which reflects the general trend of new sensors to miniaturization, multi-function, digitization, intelligence, systematization and networking. Sensor technology has undergone years of development, and safety beam sensor manufacturers believe that its development can be roughly divided into three generations:
The first generation is the structural sensor, which uses the structural parameter changes to sense and transform the signal.
The second generation is a solid-state sensor developed in the 1970s. Safety beam sensor manufacturers stated that this sensor is composed of solid components such as semiconductors, dielectrics, and magnetic materials, and is made of certain characteristics of materials. Such as: thermoelectric effect, Hall effect and photosensitive effect are used to make thermocouple sensor, Hall sensor and photosensitive sensor respectively.
The third-generation sensor is a newly developed intelligent sensor, which is the product of the combination of microcomputer technology and detection technology, so that the sensor has a certain artificial intelligence.
The above is what the safety beam sensor manufacturers share today.
