泛美奥林巴斯高压脉冲发射接收器panametrics Model 5058PR英文简介：
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 19" (483 mm) wide enclosure.

aged in a
rack adaptable 19" (483 mm) wide enclosure.
泛美奥林巴斯高压脉冲发射接收器panametrics Model 5058PR Applications：
Used with an analog
or digital oscilloscope, the Model 5058PR can be the basis of a bench top
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

panametrics Model 5058PR Standard Inclusions
The Model 5058PR is shipped with two BCB-58-4 cables, one 50 ohm terminator,
application detachable power/mains cord, and operating manual. An optional
rack-mount kit is available and should be specified at time of ordering.
