PLUG-IN MODULES
TRISONIC
TM
SCANNING MODULE. This module is utilized to
receive airborne 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 Trisonic
TM
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.
