The Probe
Range  0.25 to 5 m (0.8 to 16.4 ft)
 Process temperature  -40 to 60 °C (-40 to 140 °F)
  •  One relay, 4 to 20 mA (3-wire)
  •  4 to 20 mA (2-wire)



  • The Probe is a short-range integrated ultrasonic level transmitter, ideal for liquids and slurries in open or closed vessels.
  • The transducer is available in PVDF copolymer, making the device suitable for use in a wide variety of applications. The Probe is easy to install and maintain, and can be quickly removed for cleaning as required by the food, beverage and pharmaceutical industries.
  • The reliability of the level data is based on the Sonic Intelligence echo processing algorithms. A filter discriminates between the true echo and false echoes from acoustic or electrical noises and agitator blades in motion. The ultrasonic pulse propagation time to the material and back is temperature-compensated and converted into distance for display, analog output and relay actuation.
