Suitable for use in explosion hazardous areas. Benefits at a glance With components built to withstand high temperatures: for medium temperatures to 280 C (540 F) With welded, gas-proof bushing: highest possible safety even if sensor is damaged Large selection of process connections: universal use Process connections from ¾ and compact tuning fork: also for installing in confined spaces Wide variety of electronics, e.g. NAMUR, relay, thyristor, PFM signal output: the right connection for every process control system Monitoring of tuning fork for damage: reliable function PROFIBUS-PA protocol: commissioning and maintenance quick and easy. Areas of application: The Liquiphant S is a level limit switch for use in all liquids with a temperature between 40 C and +280 C ( F) (with no temperature shock limitation) at a pressure up to 64 bar (930 psi) at a viscosity up to 10,000 mm 2 /s at a density from 0.5 g/cm 3 The function is not affected by flow, turbulence, bubbles, foam, vibration, solid matter or build-up. The Liquiphant is thus the ideal replacement for float switches. FTL 70: Compact design, ideal for mounting in pipes FTL 71: With extension tube to max. 3 m (115 in) High corrosion-resistant Alloy C4 (2.4610) is available for the fork and process connections for applications in very aggressive liquids. EEx ia (IS), EEx de and EEx d (XP) protection allow it to be used in explosion hazardous areas. Endress +Hauser The Power of Know How
