Technical Characteristics and Environmental Focus
-
Condensate-Resistant Contite Cell: The sensor is completely protected against moisture ingress, which is critical for measurements in damp environments such as water basins or wells. This design ensures minimal temperature effects and long-term stability.
-
Foam-Independent Measurement: Because the device measures the hydrostatic pressure (weight) of the liquid column, the accuracy remains unchanged even if a thick layer of foam forms on the surface of the medium.
-
Rigid Rod Construction: The rod version is ideal for applications where the sensor must be positioned at a specific depth and maintained in a stable orientation, preventing the sensor from moving due to moderate agitation or flow.
-
High Reference Accuracy: With a standard accuracy of ±0.2% and a high-precision option of ±0.1%, it provides reliable data for both process control and inventory management.
-
Safety and Drinking Water Approvals: The FMB51 is certified for use in SIL2 safety systems and carries specific approvals for drinking water applications, ensuring it meets the stringent safety and purity standards of the environmental sector.
