Trisonic Scanning Module

A. PLUG-IN MODULES

Stethoscope Module

TRISONICTM 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. It is module shielded to provide protection from stray RF waves that have a tendency to effect electronic receiving and measurement. This 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.

DISPLAY PANEL:

In the Operation Mode the Display Panel will show intensity levels (as dB and as a bar graph), Frequency, Battery Level, and “Display Mode”. The Display Mode and the Battery level indications alternate. Intensity levels are shown simultaneously as a numeric dB value and on a sixteen segmented bar graph (with each segment representing 3 dB). The Frequency is adjustable from 20 kHz to 100 kHz. These represent the range of frequency selection capable with the Ultraprobe. The most common frequency used for general leak detection or electrical inspection is 40 kHz. These frequencies may be "tuned in" when performing inspections with any of the Ultraprobe’s plug-in modules. The Display Mode indicates the operation mode of the instrument. This is indicated on the display panel as R for Real Time, P for Peak Hold, S for Snap Shot, or RO for Real Time “Offset”, PO for Peak Hold “Offset” and SO for Snap Shot “Offset”. (For additional information about Offset see dB Scale Select in the Set Up Mode Section..
