ENDRESS+HAUSER  FTL33-AA4M2ABVAJ

The Liquiphant FTL33 is a point level switch for universal use in all liquids. It is used preferably in storage tanks, mixing vessels and pipes, where the internal and external hygiene requirements are particularly stringent.

external hygiene requirements are particularly stringent. Ideal for applications in which float switches or conductive, capacitance and optical sensors have been used up to now. The Liquiphant FTL33 also works in areas where these measuring principles are not suitable due to conductivity, buildup, turbulence, flow conditions or air bubbles.

The Liquiphant FTL33 can be used for process temperatures up to:

• 100 °C (212 °F), CIP-capable
• 150 °C (302 °F), CIP- and SIP-capable

• 3-A and EHEDG certificates
• CIP and SIP cleanability guaranteed up to 150 °C (302 °F) continuous temperature
• All-metal separation, no plastics in the process
• Robust stainless steel housing, optionally available with M12x1 connector with IP69 protection (optional)
• External function test with test magnet
• Onsite function check possible thanks to LED indication
• Compact design for easy installation even in confined conditions or hard-to-access areas

A piezoelectric drive causes the tuning fork of the Liquiphant FTL33 to vibrate at its resonance frequency. When the tuning fork is immersed in a liquid, its intrinsic frequency changes due to the change in density of the surrounding medium. The electronics system in the point level switch monitors the resonance frequency and indicates whether the tuning fork is vibrating in air or is covered by liquid.

A signal is output via the DC-PNP or AC/DC electrical connection.

The measuring system consists of a Liquiphant FTL33 point level switch, e.g. for connection to programmable logic controllers (PLC), a mini-contactor or solenoid valve.
