5. FRD Sensor FD3051ST Pressure Transmitter Measurement Accuracy Troubleshooting Guide
Measurement deviation can sometimes result from installation, wiring, environmental conditions, or incorrect configuration rather than the transmitter itself.
1. Check the Pressure Range
Confirm that the selected pressure range matches the actual operating pressure.
2. Check Installation
Inspect the process connection, pressure line, sealing, and installation condition for leakage or blockage.
3. Check Temperature
Confirm that the operating environment is within the specified −40°C to +80°C range.
4. Check Power and Wiring
Verify the 12–32 VDC power supply, wiring polarity, grounding, and output loop.
5. Check Communication
For HART or RS485 applications, verify communication settings, wiring, and configuration parameters.
6. Check Calibration
If measurement deviation remains after the above checks, verify the transmitter using a calibrated pressure source and follow the appropriate calibration procedure.
