Technical Characteristics and Environmental Resilience
-
Condensate-Resistant Contite Cell: The sensor element is hermetically sealed to prevent moisture and condensation from interfering with the electronics. This is a critical feature for environmental monitoring where sensors are submerged in cool water while the ambient air is warm and humid.
-
Suspension Mounting: The use of a mounting clamp allows for extremely fast and flexible installation. The sensor can be suspended at any depth and easily raised or lowered for maintenance without unbolting process connections.
-
Foam-Independent Accuracy: Since the device measures the hydrostatic pressure (weight) of the liquid column, the level reading remains accurate even if thick foam layers, surface turbulence, or waves are present.
-
Durable Cable Options: To match the chemical and thermal requirements of the process, the cable is available in PE (Polyethylene) for standard water use or FEP (Fluorinated Ethylene Propylene) for more aggressive media or higher temperatures.
-
Safety and Precision: The FMB53 is certified for SIL2 safety loops and carries drinking water approvals. It provides a standard accuracy of ±0.2%, with a ±0.1% high-precision option available for critical inventory tasks.
