3051 pressure transmitter

The 3051 pressure transmitter has advantages such as reliable operation, stable performance, easy installation and use, small size, light weight, and high cost-effectiveness. Widely used in various industrial automation environments, involving water conservancy and hydropower, railway transportation, intelligent buildings, production automation, aerospace, military industry, petrochemicals, oil wells, electricity, ships, machine tools, pipelines and many other industries, suitable for measuring the liquid level, density and pressure of liquids, gases or steam, and then converting the pressure signal into a 4-20mA DC signal output. Pressure transmitters can be divided into three types based on their pressure measurement range: general pressure transmitters (0.001MPa~35MPa), micro differential pressure transmitters (0-1.5kPa), and negative pressure transmitters. The product consists of a measuring film and electrodes on both sides of the insulating film, each forming a capacitor. When the pressure on both sides is not consistent, it causes displacement of the measuring diaphragm, and the displacement is proportional to the pressure difference. Therefore, the capacitance on both sides is unequal, which is achieved through oscillation and demodulation.
