1. Description
The QWB118 digital manometer is fully electronic and battery-operated, which makes on-site installation very easy. Specifically, a high-precision piezoresistive pressure sensor is used, and the output signal is processed by the high-precision low temperature drift amplifier and then sent to the high-precision A / D converter to be converted into a digital signal, the current pressure value is calculated and processed on the LCD Screen. It has advantages: flexible use, simple operation, easy troubleshooting, safe, reliable, etc. It is widely used to measure and display the pressure of the medium in hydropower, water, petroleum, chemical, mechanical, hydraulic and other industries.
