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 have a tendency to effect electronic
receiving and measurement. The Stethoscope (Contact) Module can be effectively utilized in
practically any environment ranging
from airports to broadcasting
towers. 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.
