Vibronic Point Level Switch Liquiphant FTL85

Application

The Vibronic Point Level Switch Liquiphant FTL85 is designed for hazardous environments and is certified with international safety standards. It offers fail-safe overfill protection for applications requiring functional safety up to SIL3, all with a single device. The sensor features a high corrosion-resistant coating made from materials such as enamel, ECTFE, and various PFA compounds. The FTL85 provides reliable measurements, unaffected by factors like changing media properties, flow, turbulence, gas bubbles, foam, vibration, or build-up.

Key specifications include:

• Suitable for liquids with safety requirements up to SIL3.
• Available process connections: threaded and flanged.
• Operating temperature range: -50°C to +150°C (-76°F to +300°F).
• Pressure tolerance: -1 to +40 bar (-14.5 to +580 psi).
• Customizable sensor length: extension pipe up to 3 meters (9.8 feet).
• Sensor materials: enamel, ECTFE, and various PFA coatings.
• Certified for international explosion protection, overfill protection (WHG), and SIL.

Benefits

• Ideal for safety systems requiring functional safety up to SIL3, complying with IEC 61508 Ed.2.0, IEC 61511-1, ISA 84-1, and DIN EN ISO 13849 standards.
• Extended proof testing interval of up to 12 years, with simple testing of slave devices at the press of a button.
• Continuous self-monitoring and internal redundancy for enhanced safety.
• Features a 4-20mA interface (in compliance with NAMUR NE 06/NE 43) for seamless integration with switching units (Nivotester FailSafe FTL825) or direct integration into a safety PLC, providing dual-channel output and safety locking.
• Quick, cost-effective startup with no need for adjustments.
• No moving mechanical parts, ensuring low maintenance, no wear, and extended operational life.
• Continuous monitoring of the fork for potential damage, corrosion, buildup, or mechanical blockage.
