4.1. Systems under pressure
4.1.1. Refrigerating sets of air conditioning instalations
Especially in areas where heavy wind or a concentration of fumes render
other detectors useless, the UL 23 still will function. It does not „sniff“ the
turbu
lent medium, but it „hears“ it, independently of the wind.
4.1.2. Pneumatics and Hydraulics
Leaks are quite common in pneumatic systems (controls, hoses, tools,
fittings): Listen for the rushing sound of the leak!
Large hydraulic leaks are obviously easy to see, but small ones can often
be difficult. The UL 23 will allow you to hear these leaks with ease! When
testing for hydraulic leaks use the yellow waveguide to protect any fluid
from entering the sensor.
4.1.3. Leaks behind walls or under Insulation
These are difficult to find by any method, and are also difficult with UL 23
because the drywall or insulation drastically reduces the amount of sound
present on the opposite side. Although the UL 23 was not designed to find
theses types of leaks, it has been somewhat successful finding large leaks
in these situations.
4.1.4. Electrical Arcing
A jump in electrical current or Arc, will make a popping, frying, or buzzing
noise in the ultrasonic range. The AccuTrak can be used to locate electrical
failures which are causing a decline in power quality. Use to test circuit
breakers, buss bars, relays, corrosion in contacts, or poor insulation.
Warning: Be careful, and use common sense around electrical cur-
rents! Use the plastic waveguide, and keep at a safe distance!
