PULSAR Ultrasonic Level Transducer
Pulsar’s main dB series of non contact ultrasonic transducers offer compact, robust
measurement and an innovative approach to transducer design.
Previously, users had a choice between high-voltage,
frequency dependent transducers that were susceptible to
electrical noise and needed special, protected interconnecting
cables, and weak, low-power transducers that had good
hazardous area performance but performed poorly in any but
the simplest application.
The dB range has changed all that, creating a compact, low
power transducer design that can be I.S. certified and uses
standard interconnecting cables, yet produces extremely high
acoustic power to give exceptional results in a wide variety of
Team a dB transducer with any of Pulsar’s Ultra, FlowCERT,
Zenith, Quantum or Blackbox control units to create the
perfect solution for your application. All transducers have
flammable atmosphere approval as standard.
Standard transducer bodies are made from Valox 357
PBT with a special foam radiating face. Some are
available with both body and sealed front face in PVDF
for corrosive applications.
ALL BEAM ANGLES ARE INCLUSIVE, BUT GIVE AN EFFECTIVE BEAM ANGLE OF <3 DEGREES
ON OUR CONTROLLERS. RANGE ON POWDERS AND SOLIDS DEPENDS ON APPLICATION.
* dB50 - not ATEX (flammable atmosphere) approved, and works with modified Ultra 3 and Ultra 5 controllers only
(all beam angles defined as 3dB or half power inclusive)
