Field of application
Liquiphant FTL50H is a point level switch for use in hazardous areas with all international certificates. Especially useable in the food and life sciences industry with hygienic certificates (3-A, EHEDG, ASME BPE). FTL50H offers functional safety SIL2/SIL3. Reliable measurement values, not affected by: changing media properties, flow, turbulences, gas bubbles, foam, vibrations or build-up.
Point level switch for all liquids with completely welded housing concept.
Process connections: Threads, flanges and hygienic process connection (Tri-Clamp, dairy coupling, aseptic, DRD, SMS, Varivent)
Temperature: -50 to +150°C (-58 to +302°F)
Pressure: -1 to +64bar (-14.5 to +928psi)
Sensor material: 316L
International explosion protection certificates, overfill protection WHG, SIL, hygienic certificates, marine approvals
Benefits
