5. FRD Sensor FD80B Intelligent Universal Pressure Transmitter Measurement Accuracy Troubleshooting Guide

When the FRD Sensor FD80B Intelligent Universal Pressure Transmitter shows inaccurate readings, unstable output, or abnormal signals, users can follow the troubleshooting steps below.

Step 1: Check Operating Conditions

Confirm whether the actual pressure, temperature, and measured medium are within the specified working range.

Abnormal operating conditions may affect measurement accuracy.

Step 2: Check Installation and Pressure Connection

Incorrect installation or loose connections may cause measurement deviation.

Check:

• Pressure connection

• Installation position

• Mechanical fixing

• External vibration

Step 3: Check Pressure Pipeline

Blocked pipelines, leakage, or contamination may affect pressure transmission.

Inspect:

• Pipeline blockage

• Leakage points

• Foreign materials

• Condensation

Step 4: Check Zero Point and Calibration

If the output has a constant deviation, check zero adjustment and calibration status.

Calibration may be required after long-term operation or installation changes.

Step 5: Check Temperature Influence

If measurement changes with temperature variation, verify whether the transmitter operates within the specified temperature range.

Avoid installation locations with excessive heat sources or large temperature fluctuations.

Step 6: Check Power Supply and Signal Connection

Unstable power supply or incorrect wiring may cause signal problems.

Check:

• Supply voltage

• Wiring connection

• Grounding

• Signal interference

Step 7: Check System Configuration

If the transmitter output is normal but the displayed value is incorrect, verify PLC, DCS, or control system parameters.

Ensure:

• Output range matches system settings

• Signal type is correctly configured

• Communication parameters are correct
