重要な技術的利点
-
Superior Chemical Resistance: The entire probe (rod or rope) and the process connection are coated with PFA, a fluoropolymer that is virtually inert to most chemicals. This protection prevents corrosion of the sensor hardware in environments where standard stainless steel would fail.
-
Hygienic Design: The FMP52 features gap-free transitions and hygienic process connections such as Tri-Clamp or DIN 11851. Its construction meets strict sanitary requirements, making it suitable for Clean-in-Place (CIP) and Sterilize-in-Place (SIP) cycles.
-
Reliable Interface Measurement: Like the FMP51, the FMP52 is capable of tracking the interface between two liquids (e.g., an organic solvent over an aqueous phase). The guided pulses ensure a strong reflection even from the lower layer, provided the upper medium is non-conductive.
-
Multi-Echo Tracking: The sophisticated echo evaluation software ignores interference from tank internals or agitators. It continuously tracks the level signal, even if the liquid surface is turbulent or if foam begins to form.
-
HistoROM Data Management: This system stores all device-specific data and configuration settings. In the event of an electronics replacement, the new module can be commissioned instantly by reloading the data from the HistoROM, ensuring minimal downtime.
-
Heartbeat Technology: This feature enables the device to perform self-diagnostics and verify its own health without interrupting the process. It can specifically monitor the integrity of the PFA coating and signal quality to predict maintenance needs.
-
SIL3 Safety Integrity: The FMP52 is developed according to IEC 61508 for use in safety-instrumented systems. It supports a simplified proof-testing procedure that allows for functional verification without removing the probe from the tank.
