Vibronic Point Level Switch Liquiphant FTL80

Application

The Vibronic Point Level Switch Liquiphant FTL80 is designed for use in hazardous areas and complies with international safety certifications. It provides FailSafe overfill protection in applications requiring functional safety up to SIL3 using a single device. Its performance is reliable, even in the presence of varying media properties, flow conditions, turbulence, gas bubbles, foam, vibrations, or buildup.

This point level switch is ideal for liquid applications requiring up to SIL3 certification.

• Process connections: Available with threaded and flanged options.
• Temperature range: -60 to +280°C (-76 to +540°F)
• Pressure range: -1 to +100 bar (-14.5 to +1,450 psi)
• Sensor material: 316L stainless steel, Alloy C
• Certifications: International explosion protection certificates, overfill protection (WHG), SIL, and marine approvals.

Benefits

The Liquiphant FTL80 is suitable for safety systems requiring functional safety up to SIL3, meeting standards such as IEC 61508 Ed. 2.0, IEC 61511-1, ISA 84-1, and DIN EN ISO 13849.

• Proof testing: Extended proof test intervals of up to 12 years, with slave devices that can be tested at the press of a button.
• Self-monitoring: Continuous internal diagnostics and redundancy ensure reliable operation.
• Integration: The 4-20mA interface (according to NAMUR NE 06/NE 43) allows seamless integration via the switching unit (Nivotester FailSafe FTL825) with two-channel safety contacts and locking functions, or directly into a safety PLC.
• Ease of use: No need for adjustments, enabling quick and cost-effective startup.
• Low maintenance: With no mechanically moving parts, the device is maintenance-free, wear-resistant, and offers a long operational life.
• Advanced monitoring: It actively monitors the condition of the tuning fork for potential damage, corrosion, buildup, or mechanical obstructions.
