The dBi Profibus series transducers are a range of non-contacting, ultrasonic level sensors that make use of the widely used Profibus Protocols. The self-contained level sensors are available in a variety of different measurement ranges ranging from 125 mm to 15 m (4.9 in to 49.2 ft) to suit a wide range of applications from wastewater level measurement to industrial level requirements.
The dBi Profibus non-contacting level sensors are compatible with Profibus profile 3.0.2 and provide very high resolution to give exceptional accuracy and a rapid response time of 1 second! The sensors also benefit from Pulsar Measurement's unique DATEM echo processing technology, so the level sensors are able to zone in on the true target and map out interferences. The transducers can be programmed with our PC Software or using PLC / HMI with Profibus Network.
