3 Overview

Meter is a digital display of measured pressure gauge value and can be used to measure gas, liquid and steam tables Pressure, differential pressure, absolute pressure. Instrument working principle is. the pressure measured by the mass media pressure acting on the pressure sensor, pressure sensor output phase An electric signal or a digital signal after processing by the signal processing unit directly on the monitor shows the amount of measured pressure value. Its working principle block diagram shown in Figure 1.
