We have an old ultrasonic lab scanning system that has a dry paper C-scan recorder for recording. We have the need to drive this system using instrumentation that has a 0 to 10 volt output. The specs for the recorder are 0 to 50 ma into 4k ohms. Does anyone know of an inexpensive amplifier that could be used to couple the instrumentation to the C-scan recorder?
The conformability is obtained with a flexible membrane filled with water between the transducer and
the inspected component. The coupling between the membrane and the component requires a small quantity of water or couplant. The conformable wedge combines the acoustic performance of immersion technique with good coupling and low attenuation.
