Digital pressure gauge is full electronic-structure and battery-powered, which make it very easy for on-site installation. Specifically, a high-precision piezo-resistive pressure sensor is used and the output signal is processed by the high-precision, low temperature drifting amplifier, then sent into the high-precision A/D converter to be converted into digital signal, after being computed and processed, the actual pressure value is showed on the LCD screen. It has benefits: flexible use, simple operation, easy debugging, safe, reliable etc. It is being widely used to measure and display the pressure of the medium in hydro-power, water, petroleum, chemical, mechanical, hydraulic and other industries.
