1. When measuring the liquid pressure, the installation position of the transmitter should avoid the liquid impact (water hammer phenomenon) so as to avoid over-voltage damage of the sensor.
2. When wiring, pass the cable through the waterproof connector (accessory) or the winding tube and tighten the sealing Nut to prevent rain water from leaking through the cable into the transmitter housing.
3. When freezing occurs in winter, pressure transmitters installed outdoors must take pressure to take antifreeze measures to prevent the volume of liquid in the pressure-intake opening from expanding due to ice formation, leading to sensor damage.
4, to prevent the sediment in the catheter deposition;
5, when measuring the liquid pressure, take the pressure port should be open in the side of the process pipeline to avoid sedimentation slag.
6. The pressure tube should be installed in a place where temperature fluctuations are small;
7. When measuring gas pressure, the pressure tap should be open at the top of the process pipe, and the transmitter should also be installed at the upper part of the process pipe so that the accumulated liquid can be easily injected into the process pipe.
8, to prevent pressure transmitter and corrosive or overheated media contact;
9. When measuring steam or other high-temperature medium, a condenser such as a buffer tube (coil) must be connected, and the operating temperature of the transmitter should not exceed the limit.
The correct installation and protection of the pressure transmitter ensure the application of the pressure transmitter.
How to protect the pressure transmitter to achieve the best measurement results?
The pressure transmitter adopts a special integrated module, which achieves accurate measurement and transmission of pressure changes of liquids, gases, steam, etc. through fine temperature drift, zero point, and nonlinear compensation. The pressure transmitter is the best measurement effect to be obtained, and should consider the following situations:
