dBi Profibus PA Transducer Series

The Pulsar dBi Profibus PA Transducer Series are a ranage of self-contained, intelligent non-contacting ultrasonic level measurement transducers which make use of Profibus PA communication protocols. Four range choices are available with either 3m, 6m, 10m or 15m range (10ft, 20ft, 33ft or 49ft), all of which take simplicity, convenience and accuracy to a new level.

Can be specified in various formats to suit the application, for example flanged, PTFE coated for corrosive applications, fitted with foam face or submergence shield and with threaded noses for easy installation.
