PLUG-IN MODULES
TRISONIC
TM
SCANNING MODULE.
This module is
utilized to receive air-borne ultrasound such as the ultrasounds
emitted by pressure/vacuum leaks and electrical discharges.
There are four prongs at the rear of the module. For placement,
align the prongs with the four corresponding jacks in the front
end of the pistol housing and plug in. The TrisonicTM Scanning
Module has a phased array of three piezoelectric transducers to
pick up the airborne ultrasound. This phased array focuses the
ultrasound on one "hot spot" for directionality and effectively
intensifies the signal so that minute ultrasonic emissions can be
detected.
STETHOSCOPE
(CONTACT) MODULE.
This is the module with the
metal rod. This rod is
utilized as a "waveguide" in
that it is sensitive to
ultrasound that is generated
internally such as within a
pipe, bearing housing or steam trap. Once stimulated by ultrasound, it transfers the
signal to a piezoelectric transducer located directly in the module housing.
The module is shielded to provide protection from stray RF waves that can affect
electronic receiving and measurement. It is equipped with low noise amplification to
allow for a clear, intelligible signal to be received and interpreted. For placement align
the four prongs on the back with the corresponding receptacles in the front of the
pistol and plug in.
