LT4706M7A Schneider RelayTechnical Features
The Schneider sensor industry is at a critical stage of development from traditional to new sensors, reflecting the overall trend of miniaturization, multifunctionality, digitization, intelligence, systematization, and networking of new sensors. Sensor technology has undergone years of development, and its development can be roughly divided into three generations:
*Dai is a structural sensor that utilizes changes in structural parameters to sense and convert signals.
The second generation is a solid-state sensor developed in the 1970s, which is composed of solid components such as semiconductors, dielectrics, and magnetic materials, and is made using certain properties of the materials. For example, by utilizing the thermoelectric effect, Hall effect, and photosensitive effect, thermocouple sensors, Hall sensors, and photosensitive sensors are respectively made.
The third generation of sensors is a newly developed intelligent sensor that combines microcomputer technology with detection technology, giving the sensor a certain degree of artificial intelligence.
