The transducer is the "business end" of the DX-2. It transmits and

receives ultrasonic sound waves that the DX-2 uses to calculate the

thickness of the material being measured. The transducer connects to the

DX-2 via the attached cable, and two coaxial connectors. When using

transducers manufactured by Dakota Ultrasonics, the orientation of the

dual coaxial connectors is not critical: either plug may be fitted to either

socket in the DX-2.

The transducer must be used correctly in order for the DX-2 to produce

accurate, reliable measurements. Below is a short description of the

transducer, followed by instructions for its use.

This is a bottom view of a typical transducer. The two semicircles of the

wearface are visible, as is the barrier separating them. One of the

semicircles is responsible for conducting ultrasonic sound into the material

being measured, and the other semicircle is responsible for conducting the

echoed sound back into the transducer. When the transducer is placed

against the material being measured, it is the area directly beneath the

center of the wearface that is being measured.
