NM01T8578608

Dakota — T-857-8608 Single-Element Delay Line Transducer

Overview

The Dakota T-857-8608 is a single-element delay line ultrasonic transducer designed for high-penetration thickness measurement applications. Its low 500 kHz operating frequency supports improved ultrasonic transmission through thick, attenuative, coarse-grained, or acoustically challenging materials.

Equipped with a 1 in element, the transducer provides strong acoustic energy for applications where reliable sound penetration is more important than high-resolution measurement of very thin materials. Its delay line design helps control the ultrasonic pulse and supports consistent coupling between the transducer and the inspection surface.

The top-entry BNC connector provides a secure cable connection and convenient cable routing during field, shop, manufacturing, and QA/QC inspections. SKU T-857-8608 is suitable for professional ultrasonic thickness measurement programs requiring a specialized high-penetration probe.
