3.3 FITTING THE TRANSDUCER
The transducer transmits and receives ultrasonic sound
waves that the gauge uses to calculate the speed of sound in
the material being measured.
The transducer connects to the gauge via the attached cable,
and two coaxial connectors. When using transducers
manufactured by Elcometer NDT, the orientation of the dual
coaxial connectors is not critical; either plug may be fitted to
either socket.
The transducer must be used correctly in order for the gauge to produce accurate, reliable measurements.
The illustration shows the two semicircles of the wearface and
the barrier separating them on a typical transducer.
One of the semicircles transmits ultrasonic sound into the
material being measured, and the other semicircle receives
the sound echoes back into the transducer. When the
Wearface
transducer is placed against the material being measured, it is
the area directly beneath the centre of the wearface that is
being measured.
3.4 SWITCHING ON/OFF
To switch on or off, press the on/off key
.
The gauge will switch off automatically after 5 minutes of inactivity.
