FRD FD86E Submersible Level Transmitter – Waterproof Hydrostatic Water Level Sensor
The FD86E is a submersible hydrostatic level transmitter by FRD SENSOR. It uses a high-performance piezoresistive sensor in a fully sealed stainless-steel probe, which is immersed directly in liquid to convert hydrostatic pressure into level depth. It provides 4-20mA analog output with optional HART/RS485 digital communication. Cable options include PE/PUR/PTFE, suitable for clean water, wastewater, and mildly corrosive liquids. With a compact, maintenance-free design and long-term stability, it is widely used for continuous level monitoring in pools, tanks, wells, rivers, and small-to-medium storage tanks.
