PT118 digital vacuum pressure gauge meter intelligent high precision hydraulic pressure gauge sensor is a fully electronic structure, using battery power supply, easy to install on site. The front end uses high-precision diffusing silicon sensor, the output signal is amplified by the high-precision, low-temperature drift amplifier, and sent to the high-precision A / D converter, which is converted into digital signals that can be processed by the microprocessor. After computing processing, the actual pressure value is displayed by the LCD display.The battery power supply digital display pressure gauge is flexible to use, simple to operate, easy to debug, safe and reliable. Widely used in hydropower, tap water, petroleum, chemical, mechanical, hydraulic and other industries, the pressure of fluid media measurement display
