PULSER-RECEIVER
5058PR
Model 5058PR High Voltage Pulser-Receiver
The Panametrics ® Model 5058PR High
Voltage pulser-receiver is designed
especially for ultrasonic test and
measurement applications in attenuating
mediums. The pulser section of the
Model 5058PR can deliver up to 900
volts in an impulse type excitation pulse
to appropriate low frequency transducers.
The flexible receiver section provides
switchable 40/60 dB gain with an
additional 30 dB available from an integral
low noise preamplifier. Four position high
and low pass filters and 1 dB attenuation
steps further optimize signal response.
A full range of front panel controls permits
discrete calibrated settings or continuous
adjustments for easy and repeatable
instrument setup. The unit is packaged in
a rack adaptable 483 mm (19 in.) wide
enclosure.
APPLICATIONS
Used with an analog or digital oscilloscope,
the Model 5058PR can be the basis of
a benchtop measurement system for
determination of material quality or
properties. Flaw detection, time of flight,
thickness, velocity, attenuation, and
frequency content are investigated. The
high voltage pulser and high gain receiver
of the Model 5058PR make it particularly
useful for applications that challenge the
penetrating capability of conventional
pulser/receivers in such materials as:
- Coarse grain cast metals
- Concrete, stone, soil, or sand
- Composites and fiberglass
- Very thick plastics or rubber
- Highly attenuating liquids, slurries,
or emulsions
- Wood and fiberboard
- Air gaps
