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.
