Technical principle:

This is a kind of the pressure (differential pressure) measurement and control output control technology together. Pressure part adopts diffusion silicon pressure sensor as a sensitive element, through high precision signal detection, linear amplification processing, comparison and logical operation process, and finally monitoring isolation of different pressure value output control signals.

Technical features:

Pressure switch has small volume, work stability, long service life, high accuracy, wide range of control configuration and high cost performance, can realize the pressure control alone or in combination with other data collection devices are linked together, all sorts of function of the pressure control system.

Demand for different pressure of pipe networks system of gas equipment to realize single flow control, gas handling system is the most economic status.
