Technical Characteristics and Operational Innovation
-
True 2-Wire Loop-Powered Technology: Unlike traditional 4-wire radiometric sensors that require separate power lines, the FMG50 operates entirely on a 2-wire loop. This reduces installation costs and allows for easier integration into existing control systems.
-
Non-Invasive Measurement: Because the sensor is mounted on the outside of the vessel, there is no contact with the medium. This makes it immune to process temperature, pressure, corrosion, abrasion, or toxicity.
-
High-Temperature Resilience: Innovative sensor technology allows the FMG50 to operate in ambient temperatures up to +80°C (+176°F) without the need for expensive and bulky water-cooling jackets.
-
Heartbeat Technology: Integrated diagnostics and verification (Heartbeat Technology) enable continuous monitoring of the device’s “health” and allow for documented verification without interrupting the process or shutting down the plant.
-
Safe Remote Operation: Bluetooth® wireless technology allows technicians to commission and calibrate the device from a distance, keeping them safely out of the radiation beam and away from potentially hazardous mounting locations.

Primary Applications
-
High-Pressure Reactors & Autoclaves: Monitoring level or density in environments where the vessel walls are too thick or the internal conditions too violent for contact sensors.
-
Separators and Interface Measurement: Clearly distinguishing between oil, water, and gas layers or detecting the interface between two liquids of different densities.
-
Acid Tanks and Toxic Media: Safe level detection in highly corrosive or lethal chemical storage where any potential leak point (like a sensor mounting hole) must be avoided.
-
Cyclones and Sludge Monitoring: Accurate measurement in abrasive slurries or high-viscosity solids that would damage or coat traditional probes.
-
Safety Instrumented Systems (SIS): Serving as a highly reliable safety barrier for overfill prevention (WHG) or dry-run protection in critical processes.
