Pulsar - Model dBi Profibus Series -Ultrasonic Intelligent Transducers
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 Pulsar`s PC Software or using PLC / HMI with Profibus Network.
