Background
A pressure transmitter (pressure transmitter) is a pressure sensor that uses an output as a standard signal, and is a meter that receives a pressure variable and converts the pressure variable into a standard output signal in proportion. The pressure sensor can convert physical pressure parameters of gas, liquid and the like sensed by the pressure element sensor into standard electric signals (such as 4-20 mADC and the like) so as to supply secondary instruments such as an indication alarm instrument, a recorder, a regulator and the like for measurement, indication and process regulation. The pressure transmitter is the most common sensor in industrial practice, is widely applied to various industrial automatic control environments, relates to various industries such as water conservancy and hydropower, railway transportation, intelligent buildings, automatic production control, aerospace, military industry, petrifaction, oil wells, electric power, ships, machine tools, pipelines and the like, can sense the pressure of various objects, is not only solid or liquid but also even gas, and is applied to various fields. Its interior is further referred to as a spacer, the spacer and the filling liquid in the element being conveyed to both sides of the measuring diaphragm. The pressure transmitter is a capacitor formed by a measuring diaphragm and electrodes on insulating sheets on two sides. When the pressures on the two sides are inconsistent, the measuring diaphragm is caused to generate displacement, the displacement amount of the measuring diaphragm is in direct proportion to the pressure difference, so that the capacitances on the two sides are unequal, and the signals are converted into signals in direct proportion to the pressures through oscillation and demodulation links, but the pressure transmitter is easily damaged due to electric leakage or thunderstorm.
At present, chinese patent of No. CN207472490U discloses a lightning protection type pneumatic pressure transmitter assembly, which comprises a pneumatic pressure transmitter body, wherein the pneumatic pressure transmitter body is installed on a supporting insulating sleeve, a support is arranged at the lower end of the supporting insulating sleeve, and an air inlet of the pneumatic pressure transmitter is communicated with an external air transmission pipeline through an insulating pipe.
