3051 pressure transmitter has reliable work, stable performance, easy installation and use, small size, light weight, high performance and price. Is widely used in various industrial control environment, involved in water conservancy and hydropower, railway transportation, intelligent buildings, production control, aerospace, military industry, petrochemical, oil, electric power, ships, machine tools, pipe, and many other industries, suitable for measuring the liquid level, density and liquid, gas or steam pressure, then the pressure signal into 4 ~ 20 ma DC signal output. The pressure transmitter can be divided into general pressure transmitter (0.001Mpa ~ 35Mpa) and differential pressure transmitter (0 ~ 1.5KPa), negative pressure transmitter three kinds. The product consists of a measuring diaphragm and electrodes on both sides of the insulating sheet to form a capacitor. When the pressure on both sides is inconsistent, resulting in displacement of the measuring diaphragm, and the displacement is proportional to the pressure difference, so the capacitance on both sides is unequal, through the oscillation and demodulation link.
