Applicable to CAT excavator parts E330C Oil Pressure Sensor 161-1703

The basic principle of multi-sensor information fusion technology is just like the process of human brain's comprehensive processing of information, which complements and optimizes the information of various sensors in multi-level and multi-space, and finally produces a consistent explanation of the observation environment. In this process, we should make full use of multi-source data for rational control and use, and the ultimate goal of information fusion is to derive more useful information through multi-level and multi-faceted combination of information based on the separated observation information obtained by each sensor. This not only takes advantage of the cooperative operation of multiple sensors, but also comprehensively processes the data from other information sources to improve the intelligence of the whole sensor system.

Pressure sensor is one of the most widely used sensors. Traditional pressure sensors are mainly mechanical devices, which indicate the pressure by the deformation of elastic elements, but this structure is large in size and heavy in weight, and cannot provide electrical output. With the development of semiconductor technology, semiconductor pressure sensors came into being. It is characterized by small volume, light weight, high accuracy and good temperature characteristics. Especially with the development of MEMS technology, semiconductor sensors are developing towards miniaturization with low power consumption and high reliability.

Diffusion silicon pressure transmitter

Diffused silicon pressure transmitter is made by encapsulating silicon piezoresistive pressure sensor with isolation in stainless steel shell. It can convert the sensed liquid or gas pressure into a standard electrical signal for external output. DATA-52 series diffused silicon pressure transmitter is widely used for field measurement and control of industrial processes such as water supply/drainage, heat, petroleum, chemical industry and metallurgy.
