Ultrasonic Transducers for Level Measurement

Pulsar’s (UK) new range of self-contained, intelligent non-contacting ultrasonic level measurement transducers make use of HART (4-20mA loop powered) and Profibus PA communications protocols to make plant integration simple. dBi Transducers can represent  distance, level, space, or volume as the output from the unit and are available with either 3m, 6m, 10m or 15m range. All dBi Transducers feature Pulsar’s world-leading DATEM echo processing software and are programmable either via a PC or through a proprietary calibration unit. Pulsar’s dBi Intelligent Transducers make installation simple and take accuracy to a new level for your solids or liquids application.

Pulsar’s dBi Series Transducers are low-power devices featuring Pulsar’s world-leading DATEM echo processing power for robust and reliable measurement from 125mm through to 15m (5 inches to 49 feet) depending on the unit chosen. Integration with plant systems and other equipment is straightforward. dBi Transducers support GSD, EDDL, FDT/DTM (available on request), making it easy to configure and calibrate the devices using standard PLC/HMI industry protocols, providing options to program the transducers using either a standard interface or using Pulsar’s programming parameters.

Intelligent Transducers are available as HART or Profibus PA devices in a range of models, and 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. For solids applications, dBi Transducers are compatible with Pulsar’s aiming kit for the best possible results and to measure right down to the draw-off point of a bin or silo.

dBi Intelligent Transducers provide on-board conversion for volume with a number of pre-set tank shapes, plus the ability to curve-fit to non-standard shapes. The output from the unit can represent distance, level, space, or volume.
