Critical Technical Advantages
-
Simplified Installation: The use of a suspension clamp allows the sensor to be easily lowered into a basin or well and secured at any height without needing a welded or threaded port. This makes it ideal for retrofit applications or open-channel monitoring.
-
Condensate-Resistant Contite Cell: Like its siblings in the FMB series, the FMB53 features a hermetically sealed measuring cell. This “Contite” technology prevents moisture from entering the sensor housing, eliminating the risk of drift or failure in damp environments or outdoor installations.
-
Surface-Independent Measurement: Because it relies on the hydrostatic pressure principle, the FMB53 is completely unaffected by surface foam, floating debris, or gas layers. This ensures a reliable level reading in turbulent or aerated liquids.
-
Material Flexibility: The cable is available in PE (Polyethylene) for standard water applications or FEP (Fluorinated Ethylene Propylene) for environments requiring higher chemical resistance and a slightly higher temperature threshold.
-
Safety and Approvals: Despite its simple mounting style, the PMP53 is a high-integrity device. It is designed for SIL2 safety systems, carries drinking water approvals, and is certified for WHG overfill prevention, making it suitable for hazardous or regulated environments.
-
Modular Design: The electronics and display are separate from the sensor cell, allowing for easy onsite replacement or upgrades without removing the entire cable assembly from the process.

Primary Applications
-
Water Reservoirs and Basins: Monitoring water levels in large, open-air municipal reservoirs.
-
Wastewater Lift Stations: Level control in sumps and pump stations where humidity is high and foam is common.
-
Deep Wells and Boreholes: Measuring the water table or draw-down in municipal or agricultural wells.
-
Open Channel Monitoring: Level tracking in flumes or rivers for environmental data collection.
-
Chemical Storage in Open Tanks: Providing reliable overfill prevention in large industrial basins.
