The intelligent pressure controller is a pressure measurement and control product that integrates pressure measurement, display, and control. The product's front end uses a high-precision pressure sensor. The output signal is amplified and processed by a high-precision low-temperature drift amplifier, sent to the A/D converter, and converted into a digital signal that can be processed by a microprocessor. The computationally processed signal controls two switches to measure and control the pressure of the control system. This intelligent pressure controller is flexible to use, easy to operate, easy to debug, and safe and reliable. It is widely used in industries such as hydropower, tap water, petroleum, chemical, machinery, and hydraulics, for measuring, displaying, and controlling the pressure of fluid media.
