During the operation of a pressure sensor, the following considerations should be kept in mind:
1. Prevent the transmitter from coming into contact with corrosive or excessively hot media.
2. Prevent the accumulation of sediment or debris within the impulse piping.
3. When measuring liquid pressure, the pressure tap should be located on the side of the process pipeline to avoid the accumulation of sediment or sludge.
4. When measuring gas pressure, the pressure tap should be located at the top of the process pipeline, and the transmitter should also be mounted in the upper section of the pipeline to facilitate the drainage of any accumulated liquid back into the process line.
5. Impulse piping should be installed in locations where temperature fluctuations are minimal.
6. When measuring steam or other high-temperature media, a buffer tube (such as a coil siphon) or a similar condensing device must be connected to ensure that the operating temperature of the transmitter does not exceed its specified limits.
7. During winter or freezing conditions, transmitters installed outdoors must be protected by anti-freezing measures to prevent the liquid within the pressure tap from freezing, expanding in volume, and subsequently damaging the sensor.
8. When measuring liquid pressure, the transmitter should be positioned to avoid exposure to liquid surges (such as water hammer) to prevent overpressure damage to the sensor.
9. When wiring, route the cable through the waterproof cable gland (supplied accessory) or flexible conduit, and securely tighten the sealing nut to prevent rainwater or other moisture from seeping into the transmitter housing via the cable entry point.
