Pulsatori-ricevitori
 |
The performance of high frequency ultrasonic transducers can be significantly affected by the length of the cable
between the transducer and pulser-receiver. The Panametrics-NDT Model 5627RPP-1 Remote Pulser Preamplifier permits use
of an optimum short cable in applications when setup requirements would otherwise dictate a cable length that would
degrade transducer performance. |
Features & Benefits |
• High Frequency broadband receiver (10-150 MHz)
• 24 dB gain
• Low noise
• Switchable energy control
• Pulser repetition rate 0 to 20 KHz
• Rise Time < 2nS
• Compatible with Model 5900PR Pulser-Receiver
• Able to drive 500 ft. (152 m) cable |
Applications |
The Model 5627RPP-1 is designed for imaging, flaw detection, thickness gaging, and material characterization
applications in the frequency range of 20 to 125 MHz. It is used with a host instrument, normally a Panametrics-NDT
Model 5900PR Pulser-Receiver. Receiving power and an external trigger command from the host instrument, the Model
5627RPP-1 generates an excitation pulse of selectable energy. The excitation pulse is transmitted to the transducer
through a very short (typically 12 inch/305 mm) coaxial cable. Returning echoes are amplified by a high frequency
broadband preamplifier, and then sent to the host instrument for further processing. Cable length between the Model
5627RPP-1 and the host instrument can be as great as 500 ft./152 m.
Because the cable connecting the Model 5627RPP-1 to the transducer is very short, undesirable cable effects are
minimized. However, the instruments’ ability to drive a very long cable to the host instrument provides great
mechanical flexibility in setups. For contact applications it can be easily hand-carried. Mechanical dimensions and an
interconnection diagram are on the reverse side of this data sheet. . |
