The Transducer

The transducer is the "business end" of the MMX-6 DL. It transmits and receives ultrasonic sound waves that the MMX-6 DL uses to calculate the thickness of the material being measured. The transducer connects to the MMX-6 DL 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 MMX-6 DL.

The transducer must be used correctly in order for the MMX-6 DL 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.
