Stable Industrial Pressure Instrument with Multi-protocol Output
for Full-condition Pipeline Monitoring
Product Description
The FD80A intelligent pressure transmitter is a mature
mass-produced industrial pressure measuring device from FRD SENSOR.
Adopting advanced monocrystalline silicon sensing technology, it
features compact structure and high protection grade, suitable for
pressure detection of gas, liquid and steam media. It supports
4-20mA, HART and RS485 Modbus multi-signal output, converting field
pressure values into standard industrial signals for PLC, DCS and
remote IoT systems. With strong overload resistance, impact
resistance and low temperature drift, it stably serves chemical,
water treatment, HVAC, power and other industrial automation
scenarios.
Features
- Equipped with imported monocrystalline silicon sensor, it provides
high precision, good repeatability and low long-term zero drift for
continuous accurate pressure measurement.
- Compatible with 4-20mA analog, HART and RS485 Modbus, supporting
remote range modification, data reading and network management.
- IP66 protection grade, waterproof and dustproof, anti-aging for
long-term operation in outdoor, humid and dusty environments.
- Built-in pressure buffer structure resists sudden pressure impact
and overload, preventing equipment damage from working condition
fluctuation.
- Optional 304/316L stainless steel wetted parts resist acid, alkali
and corrosion for various medium measurement.

Applications
One device realizes three functions: differential pressure
measurement, liquid level conversion and flow conversion, saving
project cost.
It operates stably under high static pressure; pipeline pressure
fluctuation will not affect measuring accuracy, suitable for
high-pressure systems.
Built-in anti-overload structure withstands single-sided
high-pressure impact and protects the sensor from field pressure
error.
Supports HART debugging and RS485 network communication for remote
calibration, range adjustment and data collection.
Full-range temperature compensation ensures excellent long-term
stability with minimal zero and span drift.
