重要な技術的利点
-
Flexible Installation for Deep Vessels: The cable-version design allows for level measurement in very deep containers or wells where a rigid rod would be impractical or impossible to install. The cable can be specified in lengths tailored to the exact depth of the application.
-
Condensate-Resistant Contite Cell: The FMB52 is equipped with the hermetically sealed Contite cell. This unique design protects the measuring element from the moisture and humidity commonly found in outdoor reservoirs or cold-liquid tanks, ensuring long-term stability and high accuracy.
-
Material-Specific Cable Options: Depending on the process requirements, the suspension cable is available in PE (Polyethylene) for standard water applications or FEP (Fluorinated Ethylene Propylene) for better chemical resistance and slightly higher temperature tolerance.
-
Unaffected by Surface Conditions: Because it measures the hydrostatic head of the liquid, the FMB52 provides an accurate level reading regardless of surface foam, heavy turbulence, or floating debris that might confuse ultrasonic or radar sensors.
-
Safety and System Integrity: Designed for SIL2 safety systems, the PMP52 also carries WHG overfill prevention and international drinking water approvals, making it suitable for both hazardous chemical storage and municipal water management.
-
Modular Maintenance: The transmitter follows a modular concept, allowing the display or electronics to be replaced independently. This “plug-and-play” capability ensures that the device can be serviced quickly without removing the entire cable and sensor assembly from the process.
