Multi Interface Compact Pressure Transmitter Precise FD80A Series For Secondary

FD80A Series Multi-Interface Compact Pressure Transmitter | Precise Pressure Monitoring Solution for Secondary Water Supply/Smart Pipe Networks in Water Industry

The FD80A Intelligent Compact Pressure Transmitter is a high-precision and high-stability pressure measurement product. The digital technology adopted by this product represents the latest application achievement in the field of sensor manufacturing. Combined with internationally advanced design and manufacturing technology for piezoresistive pressure transmitters, it implements precise digital temperature compensation and nonlinear correction, and features an integrated structural design and standardized output signals. With the advantages of small size, high precision, light weight and wide range coverage, this product is suitable for precise measurement of fluid pressure in various industries.

1. Stabilized pressure regulation of pressurization equipment in secondary water supply systems

   In secondary water supply pressurization systems of residential communities and commercial buildings, FD80A’s multiple electrical interfaces (GDM connector, M12×1 aviation plug) directly adapt to wiring ports of variable-frequency pressurization pumps from different brands, eliminating the need for adapters and improving installation efficiency by 40%. Its 0.25%FS high accuracy real-time monitors pump outlet pressure, linking with the frequency conversion system to dynamically adjust water supply pressure—avoiding water hammer risks from pipeline overpressure and water cutoff for high-rise users due to underpressure. The IP65 protection class resists humid, dusty pump room environments, ensuring long-term stable operation.

2. Distributed pipe network pressure collection for RTU terminals in smart water systems

   In the distributed pipe network monitoring system of smart water, FD80A supports MODBUS RTU/HART protocol and connects quickly to remote terminal units (RTUs) of different brands via quick-connect interfaces (e.g., M12 aviation plug). Its 0.2%FS/year long-term stability continuously outputs accurate pressure data at outdoor pipe network nodes (e.g., municipal pipe wells, community branch pipes), which is uploaded to the smart water cloud platform via RTU for leakage warning and pressure zoning regulation. The modular design of multiple interfaces also allows flexible wiring changes based on monitoring point equipment models, reducing operation and maintenance adaptation costs.

3. Inlet/outlet pressure monitoring of urban rainwater pump stations

   In urban rainwater discharge pump stations, FD80A’s multi-spec process installation interfaces (e.g., NPT thread, G thread) adapt to DN50~DN200 rainwater pipelines, installed directly at inlets and outlets: The inlet-side FD80A real-time monitors pressure corresponding to water level, warning of sudden pressure rises from pipeline blockages; the outlet-side unit monitors drainage pressure to ensure rainwater is smoothly discharged into the municipal main drainage network, avoiding pump station waterlogging. The IP65 protection class resists harsh outdoor environments (rain, sediment adhesion), adapting to 24/7 continuous pump station operation.

4. Filter press pressure control in sludge dewatering treatment systems

   In the sludge dewatering link of sewage treatment plants, FD80A’s multiple process interfaces adapt to hydraulic system ports of plate-and-frame/belt filter presses, real-time monitoring filter press chamber pressure. Its 0.25%FS high accuracy precisely controls pressure within the 0.6~1.2MPa process threshold, ensuring sludge moisture content is stably ≤80%. Its metal sensing components resist weak corrosion from sludge filtrate, and long-term stability reduces calibration frequency, adapting to the continuous operation rhythm of sludge treatment systems.
