Technical Characteristics and Process Reliability
-
Condensate-Resistant Contite Cell: The measuring cell is physically isolated from the environment, ensuring that high humidity, steam, or rapid temperature fluctuations (common in CIP/SIP cleaning) do not cause drift or failure. Active temperature compensation further minimizes thermal effects on accuracy.
-
Superior Accuracy and Stability: With a reference accuracy of ±0.075%, the FMB70 provides exceptional precision for inventory control. It is designed for best-in-class batch-to-batch repeatability and long-term stability, reducing the need for frequent recalibration.
-
HistoROM/M-DAT Data Module: This integrated memory module stores device parameters and measured values. It allows for quick plug-and-play electronics replacement and simplifies commissioning by allowing settings to be duplicated across multiple devices.
-
Two-Chamber Housing: The separation of the terminal compartment from the electronics compartment provides an extra layer of protection against environmental ingress during wiring or maintenance.
-
High-Level Safety Integration: Function-monitored from the sensor cell all the way through to the electronics, the FMB70 is suitable for safety-critical loops requiring SIL3 functional safety.
