4. MAIN APPLICATIONS

4.2 Using the ULD-400-T Ultrasonic Leak Detector Transmitter

The Transmitter allows for ultrasonic detection of openings in locations where there is no gas or

air pressure, or the pressure is not sufficient to detect the leak with the Receiver alone.

Typical applications include verifying tightness or pinpointing places of air, water or gas

leaks in:

• Fluid or gas tanks

• Building windows, doors or roofs

• Car windows and windshields

• HVAC vents

• Refrigerant pipelines

The process involves placing the Transmitter inside an object (such as tank, house or a car),

sealing the entryways and scanning the object from the outside with the Receiver to verify

tightness and pinpoint potential leaks.

1. Turn on the Transmitter.

2. Select the output signal level using the "+" or "-" signal level adjustment buttons.

Note: High setting is the default setting. For most applications and specifically for large

objects this setting is particularly useful. The High signal may cause the Receiver to read

maximum value away from the place of the leak even when lowest sensitivity was

selected. Press "-" once to get to Medium signal and press "-" again to get to Low signal

strength. Adjust signal level to allow for more precise pinpointing of the leaks.

3. Place the Transmitter inside the object to be verified and make sure entryways are sealed.

4. Preform leak detecting with the Receiver as described in section 4.1.
