PULSAR PM

The Pulsar dBi Profibus PA Transducer Series are a range 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.

High data speeds and exceptional accuracy

Pulsar use the high data speeds available with Profibus PA to provide full digital communications from a DATEM-enabled transducer. The dBi Profibus PA Transducers comply fully with communications standards IEC 61158 and Profibus PA profile 3.0.2 and provide a very high resolution to give exceptional accuracy and a rapid response time of approximately 1 second.

Programming dBi Profibus PA Transducers

Pulsar's dBi Profibus PA Transducers can be programmed either using Pulsar's PC Software or using PLC/HMI with Profibus network that:

  • supplies GSD Version 3.0 with pre-defined parameter blocks in cyclic or non-cyclic modes or;
  • supplies EDDL to provide full support for acquiring/logging of echo traces, diagnostics and full maintenance I&M functions according to IEC 61804-3 standards or;
  • supplies (on request) FDT/DTM direct to HMI software to provide enhanced diagnostic/commissioning capabilities.

DATEM Echo Processing

Pulsar's dBi Transducer Series with Profibus PA communication protocol features Pulsar's world-leading DATEM echo processing software. DATEM, Digital Adaptive Tracking of Echo Movement, allows the system to zero in on the echo from true target and follow it as it moves up and down the vessel, ignoring the stationary echoes from other elements in the measurement path. Pulsar's Profibus PA dBi Transducer Series give reliable and accurate measurement in applications where other manufacturer's equipment would not work.
