Technical Characteristics and Safety Features
-
Functional Safety (SIL2/SIL3): Developed according to IEC 61508 and IEC 61511-1, the FTL50 is certified for use in safety instrumented systems. It is an ideal choice for high-integrity overfill prevention and pump dry-run protection.
-
Second Line of Defense: For maximum environmental and operational safety, the FTL50 is available with a gas-tight feedthrough. This secondary containment barrier protects the electronics and prevents media leakage even if the sensor diaphragm is damaged.
-
Reliable Vibronic Technology: The piezo-electrically excited tuning fork operates at a specific resonance frequency. When covered by liquid, the frequency shifts, triggering the switch. This principle is unaffected by density, conductivity, or the presence of heavy build-up.
-
High-Pressure Capability: The FTL50 is designed to operate safely in process pressures up to 64 bar, making it suitable for a wide range of pressurized tanks and industrial vessels.
-
Material Versatility: While 316L stainless steel is standard, the sensor can be manufactured from high-corrosion resistant alloys for use in aggressive chemical environments.
-
Continuous Health Monitoring: The device actively monitors the condition of the tuning fork for mechanical damage or corrosion, ensuring the safety function remains active and reliable throughout its service life.
