Because explosion-proof pressure transmitters have many functions such as reliable operation, convenient installation and installation, high performance and price ratio, stable performance and high explosion-proof grade, today's explosion-proof pressure transmitters have been applied in many industrial fields. Then let's take a look at the working principle and installation precautions of the explosion-proof pressure transmitter.
First, the working principle of the explosion-proof pressure transmitter The pressure of the measured medium is transmitted to the explosion-proof transmitter through the Unicom section. The measuring head is a component that can change the capacitance. Due to the pressure, the capacitance of the measuring head The change in pressure varies. The change capacitance outputted by the measuring head is transmitted to the oscillator of the oscillating plate, and the oscillator changes the oscillating frequency according to the changed capacitance. The oscillating frequency signal is amplified by the integrated operation, and the detected half-wave signal with a small oscillating frequency is sent to the oscillating frequency. Intelligent microprocessor.
Second, the explosion-proof pressure transmitter installation notes 1, explosion-proof transmitter, must comply with the explosion-proof regulations during installation.
2. The measured medium is not allowed to freeze, otherwise the diaphragm of the sensing element will be damaged, resulting in damage to the transmitter.
3, should be installed as much as possible in the temperature gradient and humidity changes, no impact and vibration.
The above contents are the working principle and installation precautions of explosion-proof pressure transmitters. Today's pressure transmitters can be divided into: ordinary pressure transmitters, remote pressure transmitters, explosion-proof pressure transmitters, etc. In many industries, explosion-proof pressure transmitters with a high explosion-proof rating are required for work safety.
