QDB108 Intelligent Digital Pressure Gauge is
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 some benefits: flexible use, simple operation, easy
debugging, safe, reliable etc. So they have been widely
used in hydro-power, water, petroleum, chemical,
mechanical, hydraulic and other industries to measure
and display the pressure of the fluid medium.
