The Transducer
The transducer is the "business end" of the
PR-8
2
. It transmits and
receives the ultrasonic sound waves which the
PR-8
2
uses to calculate the
thickness of the material being measured. The transducer connects to the
PR-8
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
PR-8
2
.
The transducer must be used correctly in order for the
PR-8
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.
