音叉液位开关
The Liquiphant FTL64 is the ideal choice for high-temperature liquid limit detection. It makes instrument functional safety testing easy, works reliably and complies with the IEC 61508 safety standard (SIL), the API 2350 standard and the WHG standard. The vibronic sensor is based on the active safety principle, meets the requirements of limit detection for high-temperature media, reliably monitors the level, prevents tank overfill and provides pump dry-running protection. The FTL64 is easy to use and features an integrated digital interface, providing real-time data at your fingertips
Advantages
Universal limit detection principle — proven vibronic technology
Developed in accordance with IEC 61508 with high safety — meets the requirements of SIL2/3 applications (certified by a third party)
Guided operating wizard for fast, convenient execution of periodic functional safety tests, operated via SmartBlue-App, test button or external test magnet. Users can therefore test the instrument simply and quickly within the safety loop
Heartbeat Technology enables safe, uninterrupted instrument diagnostics and simple instrument self-verification
Heartbeat Diagnostics: permanent diagnostic function that increases plant safety. Connect to the instrument via SmartBlue-App to easily obtain real-time diagnostic data
Heartbeat Verification: instrument verification without interrupting the production process. Verification reports are generated automatically
Heartbeat Monitoring: track sensor data at any time with all data at your fingertips, supporting preventive maintenance and process optimization
