Because explosion-proof pressure transmitters have the characteristics of reliable operation, easy installation and use, high performance-to-price ratio, stable performance, and high explosion-proof rating, it is said that today's explosion-proof pressure transmitters are used in many industrial fields. Next, let's take a look at the working principle and installation precautions of the explosion-proof pressure transmitter.
First, the working principle of explosion-proof pressure transmitter
The pressure of the medium to be measured is transmitted to the explosion-proof transmitter through the connecting section. The measuring head is a component that can change the capacitance. Due to the effect of pressure, the capacitance of the measuring head changes with the change of pressure. The change of the measuring head output capacitance is transmitted to the oscillator of the oscillating plate. The oscillator changes the oscillation frequency according to the changed capacitance. The oscillating frequency signal undergoes an integrated operation amplification and detects the output half wave signal with a small oscillation frequency. The signal is then sent to Smart microprocessors.
Second, explosion-proof pressure transmitter installation precautions
1, explosion-proof transmitter, must meet the explosion-proof regulations during installation.
2. The measured medium is not allowed to freeze, otherwise it will damage the sensing element isolation diaphragm, resulting in damage to the transmitter.
3, should be installed in the temperature gradient and humidity change, no shock and vibration.
The above content is the working principle and installation precautions of the explosion-proof pressure transmitter. Today's pressure transmitters can be divided into: ordinary pressure transmitters, remote pressure transmitters, explosion-proof pressure transmitters, etc. In the use of reactors, explosion-proof pressure transmitters with a higher explosion-proof rating are required for the safety of work.
