Page 5: Introduction
2. INTRODUCTION Ultrasonic sound, or ultrasound, is a sound wave with frequencies above 20 kHz, higher than the upper audible limit of human hearing. Ultrasound can be generated when turbulence created by air or gas is forced through a small orifice. Leaking air or gas is generally considered to be viscous flow, and as the flow velocity increases, the frequency of the ultrasound emitted becomes higher. -

3. KIT COMPONENTS 3.3 ULD-400-T Transmitter The ULD-400-T Transmitter is included with the ULD-420 kit and is optional for the ULD-410 kit. When a leak is not pressurized sufficiently the Receiver will not be able to detect it. In these circumstances, the ULD-400-T Transmitter can be used to emit an ultrasonic sound that the Receiver can read. -

4. MAIN APPLICATIONS 4.1 Using the ULD-400-R Ultrasonic Leak Detector Receiver 1. Turn on the Receiver and plug the headphones into the jack located on the front of the Receiver. Any standard set of 3.5 mm jack headphones are compatible. 2. - Page 11 4. MAIN APPLICATIONS *ULD-400-R Filter Operation In some situations, there might be strong ultrasonic noise generated by running machinery, motion sensors or other equipment. This noise will cause the Receiver to read the maximum signal strength on the display regardless of the sensitivity settings and make it unusable for detecting leaks. In such cases, press the “Filter”...

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: •... -
