Description

Application

The Liquiphant FTL51 is a point level switch equipped with an extension tube, specifically designed for use in hazardous environments and certified with all major international approvals. It is suitable for a wide range of industries and applications, offering functional safety up to SIL2/SIL3 levels. Its robust design ensures highly reliable measurements, even in challenging conditions such as fluctuating media properties, flow changes, turbulence, gas bubbles, foam, vibrations, or material buildup.

This point level switch is ideal for detecting levels in all types of liquids and is available with various process connections, including threads, flanges, and hygienic connections like Tri-Clamp.

  • Temperature range: -50 to +150°C (-58 to +302°F)
  • Pressure range: -1 to +100 bar (-14.5 to +1,450 psi)
  • Sensor material options: 316L stainless steel, Alloy

The device is certified for international explosion protection, WHG overfill protection, and SIL compliance.

 


Benefits

  • Certified for safety systems requiring SIL2/SIL3 functional safety, in compliance with IEC 61508 and IEC 61511-1.
  • Equipped with international explosion protection and WHG overfill protection certificates.
  • Requires no calibration and is easy to commission.
  • With no mechanically moving parts, the device ensures low maintenance, no wear, and long operational life.
  • Continuous monitoring of the fork sensor for damage guarantees reliable operation.
  • Features a second line of defense to safeguard the environment.
  • Available with a variety of standardized process connections to suit diverse applications.
  • Constructed with high-grade materials such as stainless steel (316L) and corrosion-resistant alloys for enhanced durability.
