The device is a vibration limit switch for use in all liquids.
for temperatures from -50 °C to +150 °C
for pressures up to 100 bar
for viscosities up to 10000 mm 2/s
for densities up to 0.5 g/cm 3 or 0.4 g/cm 3 (other settings available on request)
The function is not affected by flow, turbulence, bubbles, foam, vibration, bulk solids content or build-up, the device is thus the ideal substitute for float switches.
The device is available with extension tube up to 6 m.
High corrosion-resistant Alloy C22 is available for the tuning fork and process connection for applications in very aggressive liquids.
Specific versions are suitable for use in explosion-hazardous areas.
The device is operated via push buttons and DIP switches on the electronic insert.
Status and faults of the device are optionally indicated via a LED module or via Bluetooth in the P+F Level app.
