About the dBi-M
Functional Description
The dBi-M transducer range has been specified and designed to meet the
demanding requirements of today’s process level measurement applications
for liquids and solids.
The transducers are compatible with RS-485 Modbus communications. They
are able to be easily set-up using a PC with an RS-485 adapter and Pulsar
dBi-M PC software.
Easy calibration and maintenance free “fit and forget” performance meaning
that you can install the dBi-M transducer level monitoring system rapidly
and with confidence, with calibration being achieved either by using a
Modbus RT
U programmer/calibrator, or via Pulsar’s free dBi -M PC software.
The dBi-M units are based on a PZT ceramic transducer element. The
nominal beam angle is 10
o (-3dB). When coupled with the DATEM ® signal
processing they provide unmatched performance in industrial process level
measurement. All transducers have integral temperature compensation.
Optional submersion shields are available to prevent spurious signals if the
transducer becomes submerged. A range of flange mounting options are
available, with optional PTFE facing for improved chemical resistance.
The dBi-M series of transducers have an RS485 digital output which can be
programmed to give readings according to
level, space, distance, or
volume .
