Technical Characteristics and Solids Performance
-
Unmatched 125m Range: Designed for the largest industrial silos and bunkers, the FMR67 maintains a stable signal even at extreme depths of 125 meters. This makes it ideal for the mining, cement, and grain industries.
-
80 GHz Beam Focusing: The high-frequency W-band allows for a very tight emitting angle. This precision enables the sensor to “see” past internal vessel fittings, such as reinforcement braces or ladders, and avoids signal interference from silo walls in narrow geometries.
-
Innovative Drip-Off Antenna: The antenna is constructed from PTFE with a specialized drip-off shape. This design minimizes the accumulation of dust and moisture on the antenna surface, ensuring maximum system availability in environments prone to buildup.
-
Heartbeat Technology: This smart functionality provides continuous self-monitoring and on-demand verification without interrupting the process. It can detect anomalies such as antenna coating or buildup, allowing maintenance teams to act before a measurement failure occurs.
-
Safety and SIL Compliance: Developed for SIL 3 applications (in homogeneous redundancy), the FMR67 offers a simplified proof test concept for SIL. This reduces operational costs and engineering effort while ensuring the highest level of plant safety.
-
HistoROM Data Management: An integrated memory module stores all device configuration and event logs. This facilitates fast and easy commissioning and ensures that parameters are automatically restored if electronics are replaced.
