Liquiphant FTL63 – hygienic point level switch for liquids
Field-proven, easy to use and ideal for hygienic applications.
Advantages
Universally suitable for all pumpable liquids without medium adjustment - proven vibronic measuring technology
Certified hygienic design (3-A, EHEDG, ASME BPE) and verified material consistency and traceability through declarations and certificates (e.g. EC1935/2004, FDA and cGMP) ensure high process and product safety
Function test via test button or magnetic pin for simple commissioning and minimized maintenance work
Thanks to Heartbeat Technology, continuous diagnostics as well as traceable and documented on-demand verification without interrupting the process
Intuitive operation via Bluetooth® technology and optical process status indication via colored and bright LEDs
Field of application
The Liquiphant FTL63 was developed specifically for the food and beverage and life sciences industries and meets all hygienic requirements. The proven vibronic technology works reliably in all pumpable liquids, even where other measuring principles reach their limits due to changes in conductivity or dielectric constant (DC value), deposits, foam, turbulence or bubbles. The technology is therefore the perfect alternative to float switches and capacitive or optical sensors.
The Liquiphant FTL63 is used for point level detection in process tanks, storage tanks and pipes.
Process temperature from -50 to +150 °C (-58 to +302 °F)
Viscosity up to 10,000 mm2/s (cSt)
Sensor length up to 3 m (10 ft)
Surface finish: mechanical or electropolished
International hygienic certificates (3-A, EHEDG, ASME BPE), wetted materials comply with EC1935/2004, FDA, GB4806
International explosion protection certification, WHG overflow protection, SIL
