The 5058PR High Voltage ultrasonic pulser-receiver is designed especially for test and measurement applications in sound-attenuating mediums. The pulser section can deliver up to 900 volts in an impulse type excitation pulse to appropriate low frequency transducers.
Описание: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. Features & Benefits• High voltage pulser, switched settings or continuously adjustable to 900 volts
ApplicationsUsed 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:
