What should be paid attention to when using pressure sensor?

Release date: September 3, 2020 Hits: 114
Any machinery in the use of the process will have a certain amount of wear, so we should pay attention to the daily use, so as to prevent mechanical damage. So we should pay attention to in use, let's learn about the matters needing attention in the process of using pressure sensor together!

What should be paid attention to when using pressure sensor?

1. Prevent the transmitter from contacting with corrosive or overheated medium, and prevent dross from depositing in the pipe;

2. When measuring the liquid pressure, the pressure tap should be opened on the side of the process pipe to avoid sedimentation and slag deposition; when measuring the gas pressure, the pressure tap should be opened at the top of the process pipe, and the transmitter should also be installed on the upper part of the process pipe, so that the accumulated liquid can be easily injected into the process pipe.

3. The pressure pipe should be installed at the place where the temperature fluctuation is small; when measuring steam or other high-temperature medium, it is necessary to connect the condenser such as buffer pipe (coil) to ensure that the working temperature of the transmitter does not exceed the limit.

4. When freezing occurs in winter, antifreeze measures must be taken according to the transmitter installed outdoors, so as to avoid the damage of the sensor caused by the expansion of liquid in the pressure port due to icing volume.

5. When measuring the liquid pressure, the installation position of the transmitter should avoid the impact of the liquid (water hammer phenomenon), so as to avoid the sensor damage due to overpressure.

6. When wiring, put the cable through the waterproof joint (accessory) or flexible pipe and tighten the sealing nut to prevent the rainwater from leaking into the transmitter housing through the cable.
