Critical Technical Advantages
-
Elite Accuracy and Stability: The FMB70 provides a standard accuracy of ±0.1%, with a “Platinum” option reaching ±0.075%. This performance is backed by active temperature compensation, ensuring minimal drift even in processes with fluctuating thermal conditions, which is essential for precise batch-to-batch repeatability.
-
Condensate-Resistant Contite Cell: The hermetically sealed Contite cell is uniquely designed to be impervious to humidity and condensation. This is a critical advantage in “cold” applications (e.g., chilled water or dairy) where moisture ingress often causes standard sensors to fail or drift.
-
High-Level Safety (SIL3): Designed according to IEC 61508, the FMB70 is suitable for use in SIL3 safety systems (in redundant configurations). This makes it a preferred choice for high-integrity overfill prevention and safety-critical process monitoring.
-
HistoROM/M-DAT Data Module: This integrated module acts as the “brain” of the device, backing up all instrument settings and measured values. It allows for fast commissioning and simplifies maintenance by enabling “plug-and-play” electronics replacement without data loss.
-
Two-Chamber Housing: The separate terminal and electronics compartments provide an extra layer of protection. This design prevents moisture or contaminants from entering the sensitive electronics area during field wiring or maintenance.
-
Comprehensive Self-Monitoring: The device is function-monitored from the measuring cell all the way to the electronics. This continuous self-diagnosis ensures that any internal anomalies are detected immediately, maintaining process safety and reliability.
