1. Introduction
Shandong FRD Sensor FD3051SDP differential pressure transmitter is
a high-performance, high-stability measuring instrument designed
for industrial automation and process control, widely used for
pressure, differential pressure, and level measurement in
petroleum, chemical, electric power, and metallurgy sectors.
2. Why Choose This Model?
- Addressing customer pain points such as zero drift caused by
alternating static pressure and temperature in complex working
conditions, sensor damage from insufficient overload capacity, and
joint leakage in harsh environments, the FD3051SDP features
advanced piezoresistive/capacitive silicon sensor technology,
superior static pressure and temperature compensation, and dual
overload protection diaphragms to ensure accurate and reliable
long-term operation while significantly lowering maintenance costs.

Measurement Accuracy Troubleshooting Guide
If abnormal output signals or inaccurate readings occur,
troubleshoot as follows: 1. Check if the positive and negative
impulse lines and valves are clear and leak-free; 2. Calibrate the
transmitter zero point, and perform zero trimming via HART
communicator or buttons if necessary; 3. Confirm whether the
working static pressure and ambient temperature are within rated
limits; 4. Check if the power supply voltage is stable (meets the
24VDC requirement).
