Precautions for Using Industrial Pressure Transmitters

1. Scope of application of industrial pressure transmitter

Pressure transmitter is the most commonly used sensor in industrial practice. It is widely used in various industrial automation environments, involving water conservancy and hydropower, railway transportation, intelligent buildings, production automatic control, aerospace, military, petrochemical, oil wells, electric power, ships, machine tools, pipelines and many other industries.

2. What aspects should be paid attention to when using industrial pressure transmitter?

(1) Prevent the transmitter from contacting overheated media

(2) Prevent dross from depositing in the duct

(3) When measuring liquid pressure, the pressure tap should be opened on or on the side of the process pipeline to avoid precipitation and accumulation of slag.

(4) When measuring gas pressure, the pressure tap should be opened at the top of the process pipeline.

(5) The pressure guiding tube is installed in a place with small temperature fluctuations

(6) When measuring steam or other high-temperature media, industrial pressure transmitters need to be connected with a buffer tube (condensers such as coils, and the working temperature of the transmitter should not exceed the limit).

(7) When freezing occurs in winter, we must take anti-freezing measures for the transmitter installed outdoors to prevent the liquid in the pressure inlet from expanding due to icing and causing damage to the sensor.

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

(9) When wiring, pass the cable through the water joint or winding tube and tighten the sealing nut to prevent rainwater from leaking into the shell of transmitter through the cable.
