Assistance technique

The 5627RPP-1 ultrasonic preamplifier permits use of an optimum short transducer cable to avoid degradation due to attenuation and cable reflections. It can be handheld or mounted to a structure and drive up to 500 feet of cable back to the 5900PR host receiver for remote applications.

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 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

• Pulser repetition rate 0 to 20 KHz
• Rise Time < 2nS
• Compatible with Model 5900PR Pulser-Receiver
• Able to drive 500 ft. (152 m) cable


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 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.
