FRD Sensor provides flexible OEM & ODM customization services for FD80A based on different industrial applications and system integration requirements.
Key customization options include:
These options help equipment manufacturers and system integrators integrate FD80A into different pressure measurement systems efficiently.
When FD80A shows abnormal pressure readings, follow these steps:
Step 1: Check the Power Supply
Verify that the supply voltage is stable and within the specified range.
Step 2: Check the Process Connection
Inspect the pressure connection for leakage, blockage or improper installation.
Step 3: Check the Zero Point
Verify the transmitter for zero-point deviation under the specified reference condition.
Step 4: Check Temperature Conditions
Confirm that the ambient and process temperatures are within the applicable range.
Step 5: Check the Output Signal
Measure the 4–20 mA output and compare the signal with the actual pressure.
If the problem persists, contact FRD Sensor for technical support.
The FRD Sensor FD80A Industrial Pressure Transmitter combines stable pressure measurement, digital compensation and flexible industrial configurations to provide a reliable pressure monitoring solution for machinery, process control and automation systems across a wide range of industrial applications.
