displacement sensor

displacement sensorThe key points during use, the correct installation position of the transmitter on the process pipeline, and the measured medium are related. In order to obtain effective measurement results, the following situations should be considered:

1. Prevent the transmitter from coming into contact with corrosive or overheated media;

2. Prevent sediment from settling inside the conduit;

When measuring liquid pressure, the pressure tap should be opened on the side of the process pipeline to avoid sedimentation and slag accumulation.

4．displacement sensorWhen measuring gas pressure, the pressure tap should be opened at the top of the process pipeline, and the transmitter should also be installed at the upper part of the process pipeline to facilitate the injection of accumulated liquid into the process pipeline.

5. The pressure conduit should be installed in a location with minimal temperature fluctuations;

When measuring steam or other high-temperature media, a condenser such as a buffer tube (coil) should be connected, and the operating temperature of the transmitter should not exceed the limit.

7．When freezing occurs in winter, anti freezing measures must be taken for transmitters installed outdoors to prevent the liquid in the pressure inlet from expanding due to freezing volume, which may cause damage to the sensor.

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

9. When wiring, thread the cable through the waterproof joint (accessory) or flexible tube and tighten the sealing nut to prevent rainwater and other substances from leaking into the transmitter housing through the cable.

The function is to convert the controlled variable measured by the measuring element into the signal type required by the controller.
