OPTIMA Delay Line Contact Transducers

OPTIMA Delay Line Contact Transducers have primary applications in precision thickness gaging and for near-surface, high-resolution flaw detection.  Relatively smooth surfaces and fairly thin test objects are generally required for best results.
Delay Line Models are available with both permanent and replaceable delay lines to further enhance the flexibility of this series.  Permanent Delay Line Models offer superior handling stability, while Replaceable Delay Lines can be contoured for special applications of replaced when worn.

Features - OPTIMA Delay Line Models utilize a plastic stand-off (the delay line) to separate the small echo from the delay-line/test-material interface and the very high amplitude initial pulse-echo at the face of the active element.  With a smaller amplitude entry surface echo and higher resolution, more precise distance/thickness measurements can be made than from standard contact transducers.  All OPTIMA Delay Line transducers are highly damped and produce best results when used with instruments having broadband receiver channels.

Stainless steel cases with OPTI-GRIP surfaces make handling comfortable and easy, with positive control "feel".  Color-coded labels permit frequency selection at a glance, and have a wear-resistant coating to protect the label information.
