Description
I. usage
The explosion-proof pressure transmitter is a device commonly used in industrial practice to convert pressure into pneumatic signal or electric signal for controlling and transmitting. It can transform the physical pressure parameters such as gas and liquid into standard electrical signals (such as 4~20mADC, etc.), and supply two indicators such as alarm, recorder and regulator to measure, instruct and adjust process. It is widely used in various industrial automatic control environment. It involves many industries such as water conservancy and hydropower, railway transportation, intelligent building, production automation, aerospace, military industry, petrochemical, oil well, power, ship, machine tool, pipeline, medical treatment, food and so on.
