Pressure is one of the important parameters in the industrial production process, and in order to ensure the normal operation of production, the pressure must be monitored and controlled. For example, in chemical reactions, pressure affects both the mass balance and the speed of chemical reactions, so process operating procedures must be strictly followed.
Secondly, pressure measurement or control is also necessary for safe production, and pressure monitoring can prevent damage or explosion of production equipment due to overpressure in time. In thermal power plants, the negative pressure of the furnace reflects the balance between the air supply volume and the induced air volume, and the pressure of the furnace is also closely related to the stable combustion in the furnace, which directly affects the safe and economical operation of the unit.
Because of the importance of pressure measurement, the selection of pressure instruments has become crucial. Our technicians have summarized the following points for your reference.
First, when transmitting with standard signals (4~20mA), pressure transmitters should be selected.
Second, in flammable and explosive occasions, isolated explosion-proof pressure transmitters or intrinsically safe explosion-proof pressure transmitters should be selected.
Third, crystallization, scarring, blockage, viscosity and corrosive media should be selected flange pressure transmitter. Materials that are in direct contact with the medium must be selected according to the characteristics of the medium.
Fourth, the pressure gauge can be selected when the use environment is good, the measurement accuracy and reliability requirements are not high.
Fifth, when measuring micro pressures (less than 500Pa), a micro differential pressure transmitter can be used.
