1.4 Transducers and Reference Standards
.
Section 3.0, Transducer Selection, contains detailed information regarding the selection and
application of ultrasonic transducers for use with The TG400. For best results, use transducers from
the OPTIMA line of transducers produced by NDT Systems, Inc. A free catalog will be sent on request
by contacting Customer Information at NDT Systems, Inc., 17188 Georgetown Lane, Huntington
Beach, CA 92647, phone (714) 893-2438, FAX (714) 897-3840. In many cases, equivalent
transducers produced by other manufacturers will also yield acceptable results.
It should be kept in mind, though, that no matter how capable the ultrasonic instrument, system
performance and test results are highly dependent upon the characteristics, performance, and
appropriate selection of the transducers used. Also, The TG400 incorporates an automatic probe
recognition feature where many NDT Systems, Inc., Nova transducers will be recognized and a basic
instrument setup invoked for the specific transducer type.
Many common reference standards are also available from NDT Systems, Inc. For custom reference
standards or test blocks, contact Customer Information at the address on the cover.
