The intelligent pressure switch is an intelligent digital pressure measurement and control product that integrates pressure measurement, display, output, and control. The product is an all-electronic structure. The front end adopts a hydraulic pressure damper sensor with an isolation membrane. The output signal is amplified by a high-precision, low-temperature drift amplifier, and sent to a high-precision A/D converter, which is converted into a digital signal that can be processed by a microprocessor. After the operation of the signal control two-way switch, the control system pressure measurement and control. The intelligent digital pressure switch is flexible, simple to operate, easy to debug, and safe and reliable. It is widely used in hydropower, tap water, petroleum, chemical, mechanical, hydraulic and other industries to measure and control the pressure of the fluid medium.
