FRD SENSOR FD80A High-Precision Intelligent Pressure Transmitter with Multi-protocol Output and Monocrystalline Silicon Sensor

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.

• 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.

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.
