FD80F Sanitary Flush Diaphragm Pressure Transmitter: Reliable Pressure Measurement for Hygienic Processes
Product Details
The FRD Sensor FD80F Sanitary Flush Diaphragm Pressure Transmitter is designed for hygienic process applications in food, beverage, pharmaceutical, dairy and biotechnology industries.
With a flush diaphragm design, digital temperature compensation and nonlinear correction, FD80F helps minimize media residue and dead spaces while supporting high-temperature configurations for demanding hygienic processes.
Hygienic pressure measurement often faces challenges such as media residue, difficult cleaning, bacterial growth, temperature effects and clogging of conventional pressure connections.
FD80F addresses these challenges with:
- Flush diaphragm design to minimize dead spaces and media residue.
- 3-A hygienic design for food, beverage and pharmaceutical applications.
- Stable measurement with digital temperature compensation and nonlinear correction.
- High-temperature option with process temperatures up to 180°C.
- Flexible outputs including 4–20 mA, HART and RS485.
- High protection options up to IP65/IP68.

When FD80F shows abnormal pressure readings, follow these steps:
Step 1: Check the Hygienic Process Connection
Verify that the Tri-Clamp or other process connection is correctly installed and check for leakage.
Step 2: Check the Diaphragm
Inspect the flush diaphragm for media residue, deposits or mechanical damage.
Step 3: Check the Zero Point
Verify the transmitter zero point under the specified reference condition and perform zero calibration if necessary.
Step 4: Check Temperature Conditions
Confirm that the process and ambient temperatures are within the specified operating range.
Step 5: Check Output & Communication
Verify the 4–20 mA, HART or RS485 signal and related communication parameters.
If the issue persists, contact FRD Sensor for technical support.
