Dakota Single Element Transducers are ultrasonic probes designed for precise thickness measurement of thin materials. They address a specific measurement problem: thin walls produce closely spaced echoes that ordinary probes struggle to separate, so accurate readings on thin stock need a transducer built for high resolution at short range.

A single element transducer uses one crystal housed in the casing, and that single crystal both transmits and receives the sound energy. The probes are commonly supplied with a delay line, which separates the transmit pulse from the return echo and so allows precise measurement on thinner materials. The range covers frequencies from 10.00MHz up to 20.00MHz, with probe diameters of 3/16 and 1/4 inch and a choice of delay line, pencil, 1/16 inch tip, 90 degree right angle and standard styles. Connector options include microdot, Lemo and BNC, and the probes suit gauges such as the FX70, FX80, PZX, PMX and PMX4. The standard elements are undamped.

These transducers are used by non-destructive testing technicians and quality inspectors measuring thin sheet, tube and component walls where standard probes cannot resolve the thickness. Dakota Single Element Transducers are supplied in South Africa by BAMR, the country's authorised distributor.
