Routine maintenance of pressure transmitter

From: Issued date 2020.01.14 Back

Pressure transmitter is the most commonly used instrument and equipment in modern industrial control. Whether it can work normally affects the normal operation of industrial production. However, whether it is a domestic transmitter or an imported transmitter, some faults will inevitably occur during use, and various faults will occur in the working environment, improper human operation or the transmitter itself. Therefore, good daily maintenance can extend the life of the product. Editor will take you to understand how to regularly maintain the pressure transmitter:

Inspection tour

Check the indication of the instrument for any abnormality to see if it fluctuates within the specified range; for some transmitters that do not have on-site instructions, go to the control room to see its secondary indication. If there is any debris around the meter or if there is dust on the meter surface, it should be removed and cleaned in time. There are errors such as leakage and corrosion between the instrument and the process interface, the impulse tube and the valves.

2. Periodic inspection

(1) For some meters that do not need to be checked every day, they should be checked at regular intervals. Periodic zero-point inspection. Because the transmitter has a secondary valve or a three-valve or five-valve group, the zero-point inspection is very convenient and does not require much time. Drain, condense and vent regularly.

(2) Regularly purge the impulse tube of the easy-to-clog media and fill with isolation fluid.

(3) Regularly check the transmitter components for completeness, no serious rust and damage; clear nameplates and logos; the fasteners must not be loose, the connectors have good contact, and the terminal wiring is firm.

(4) Regularly measure the line on site, including whether the input and output circuits are intact, whether the line is open, short-circuited, and whether the insulation is reliable.

(5) When the transmitter is running, its casing must be well grounded. The transmitter used to protect the system shall have measures to prevent power failure, short circuit, or open circuit.


(6) In the winter season, the insulation and heat tracing of the source pipeline of the instrument should be checked to prevent the source pipeline or the measuring element of the transmitter from being damaged by freezing.

During the use of the product, major or minor faults will occur. As long as we operate and maintain it in the correct way, it can extend the service life of the product. Of course, daily maintenance is important, but the choice of product is more important. Choosing the right product can avoid many unnecessary troubles.
