2 Wire Ultrasonic Level Sensor from Endress+Hauser

• The Prosonic M FMU 44 Ultrasonic Sensor can be used for the non contact level measurement of fluids, pastes, sullage and coarse bulk materials
• Endress+Hauser’s Prosonic M FMU 44 is suitable for all industries with storage facilities, particularly in the primary and resource sectors
  
  
• This compact sensor is an ideal solution for remote inventory control and silo depot sites as well as in remote solar powered situations

Benefits of the Prosonic M FMU 44 2 Wire Ultrasonic Level Sensor

• Cost effective
• Measure levels beyond 12 metre distances in storage vessels
• Technological advances within Endress+Hauser’s family of Prosonic M industrial ultrasonic level sensors have effectively doubled FMU 44’s measuring range over the previous model
• Preferred choice for all industries and basic applications where ultrasonic technology devices are suitable, not too dusty, not a vacuum, not high temperature, not high pressure and no vapour

Features of the Prosonic M FMU 44 from Endress+Hauser

• The frequency is 30kHz and pulse repetition is 0.3Hz
• The enclosure is IP68 rated and can be supplied with internal overvoltage protection
• The sensor’s accuracy is ±0.2% of set range and allowed process/ambient temperature is -40°C to +80°C
• The new level sensor is available as 4 to 20mA/ HART, in Profibus PA and Foundation Fieldbus platforms
• The FMU 44 complies with normal 4 to 20mA loop power wiring and operates on 14 to 36Vdc or down to 10Vdc when used in HART mode with fixed 11mA consumption
• The fully PVDF (polyvinylidene fluoride) Encapsulated Chemical Resistant Sensor has a blocking distance of 0.5m and  installations in 400mm, tall narrow nozzles are possible
