Transducer
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.
The transducer is the „business end“ of the MINITEST
403. It transmits and receives the ultrasonic sound
waves which the MINITEST 403 uses to calculate the
thickness of the material being measured. The trans-
ducer connects to the MINITEST 403 via the attached
cable, and two coaxial connectors. When using
transducers manufactured by the same supplier, the
orientation of the dual coaxial connectors is not critical:
either plug may be fitted to either socket in the MINI-
TEST 403.
The transducer must be used correctly in order for the
MINITEST 403 to produce accurate, reliable
measurements. Below is a short description of the trans-
ducer, followed by instructions for its use
