Technical Characteristics and Performance
-
Vibronic Measuring Principle: The tuning fork is piezo-electrically excited and vibrates at its resonance frequency in air. When the fork is covered by liquid, the frequency changes; this shift is detected and converted into a switching signal.
-
Hygienic Design and Compliance: The FTL43 is built with 316L stainless steel and features a surface finish designed to meet stringent hygienic requirements. It holds certifications for 3-A and EHEDG, ensuring it can be safely used in CIP (Clean-in-Place) and SIP (Sterilization-in-Place) processes.
-
Heartbeat Technology: This integrated diagnostic suite allows for documented on-demand verification of the sensor’s health without interrupting the process. It ensures the measurement remains reliable over the entire life cycle and simplifies safety proof-testing.
-
Plug & Play Functionality: Designed for maximum ease of use, the FTL43 requires no media adjustment. Once installed, it is ready to operate immediately, significantly reducing commissioning time for skids and modular systems.
-
Configuration Integrity (CRC): To enhance process safety, the device uses a checksum algorithm (CRC). This ensures that safety-relevant parameters are locked and haven’t been modified inadvertently, providing high confidence in overfill protection loops.
-
Digital Communication: The switch offers versatile connectivity options, including IO-Link, which enables seamless integration into modern automation architectures and provides more granular diagnostic data than a standard switch.

Aplikasi Utama
-
Pump Dry-Run Protection: Protecting centrifugal or positive displacement pumps from damage by detecting the absence of liquid in suction pipelines.
-
Narrow Skids and Modules: Its compact design makes it the ideal choice for integration into compact process modules where traditional, larger sensors cannot fit.
-
Overfill Prevention: Acting as a high-level alarm in fermentation tanks, mixing vessels, or storage tanks to prevent product loss and environmental hazards.
-
Media Separation: Reliable detection of different media even when densities change slightly, provided the liquids remain pumpable.
