Maintenance: Extend equipment lifespan and ensure measurement accuracy

The maintenance of flange diaphragm pressure transmitters should be based on the characteristics of the medium (such as corrosiveness and viscosity) to establish a maintenance cycle. The core maintenance items are as follows:

Regular inspection (cycle: 1-3 months)

Appearance inspection: Wipe the surface of the diaphragm (with a soft cloth to avoid scratches), check whether the flange sealing surface leaks, and whether the cable joints are loose;

Accuracy verification: Use a standard pressure calibrator to compare the measured value of the transmitter with the standard value. If the deviation exceeds the allowable range (such as the allowable deviation of 0.1 level transmitter being ≤± 0.1% FS), recalibrate the range and zero point.

Maintenance of special media (such as viscous and easily crystallizable media)

Regular cleaning: Disassemble the flange every 1-2 months (after power failure), clean the diaphragm and pressure pipe with suitable solvents (such as water, alcohol), and remove residual media (to prevent crystal blockage or corrosion);

Diaphragm protection: If the medium contains particles, a "filter screen" (aperture<1mm) can be installed in front of the flange to prevent particles from hitting the diaphragm and causing damage.

Long term disuse treatment

After power failure, close the front and rear valves of the transmitter and drain the medium in the pressure pipe;

If it has been out of use for more than 3 months, the transmitter should be removed, cleaned, and stored in a dry, room temperature environment (avoiding direct sunlight). The diaphragm should be coated with rust proof oil (316L material) or special protective agent (PTFE material).

Precautions (Safety and Compliance)

safe operationWhen dealing with corrosive and high-temperature media, protective equipment (goggles, anti-corrosion gloves) must be worn. Before disassembling the flange, it is necessary to confirm that the pipeline has been depressurized (to prevent injury from media spraying);

Explosion-proof requirementsIf used in flammable and explosive environments (such as chemical workshops), explosion-proof transmitters (such as Ex d IIB T4 Ga) should be selected. During installation, ensure that the explosion-proof surface is not damaged and the cable sealing meets explosion-proof standards;

Calibration RecordRecord the date, operator, and calibration data for each calibration and maintenance, establish equipment files for easy traceability of the cause of the malfunction.

Through the above steps, it can be ensured that the flange diaphragm pressure transmitter achieves accurate and stable pressure measurement in industrial scenarios, while maximizing the service life of the equipment and reducing operation and maintenance costs.
