The ULTRAPROBE 100 provides easy, accurate leak detection and mechanical inspection through advanced ultrasonic technology. Before you begin testing, it is advisable to familiarize yourself with the basic components of your kit. 1. PISTOL HOUSING The main component of the Ultraprobe is its' pistol housing. From back to front, let's examin[...]

2. SCANNING MODULE This module is utilized to receive air-borne ultrasound such as the ultrasounds emitted by pressure leaks and electrical discharges. To use, make sure it is plugged in to the front end of the metered pistol housing by aligning the plug with the receptical and inserting it firmly. To use the Scanning Module: 1. Plug in to front en[...]

To use the WARBLE TONE GENERATOR : 1. Turn Tone Generator on by selecting either "LOW" for a low amplitude signal (usually recom mended for small containers) or "HIGH" for high amplitude. In high, the Warble Tone Generator will cover up to 4,000 cubic feet (121.9 cu. meters) of unobstructed space. When the Tone Generator is on, [...]

-4- UL TRAPROBE APPLICA TIONS 1. LEAK DETECTION This section will cover airborne leak detection of pressure and vacuum systems. (For information concerned with internal leaks such as in Valves and Steam Traps, refer to the appropriate sections). What produces ultrasound in a leak? When a gas passes through a restricted orifice under pressure, it is[...]

-5- B. TO CONFIRM A LEAK: Position the Scanning Module, or the rubber focusing probe (if it is on the scanning module) close to the suspect leak site and move it, slightly, back and forth, in all directions. If the leak is at this location, the sound will increase and decrease in intensity as you sweep over it. In some instances, it is useful to po[...]

-6- D. LOW LEVEL LEAKS In ultrasonic inspection of leakage, the amplitude of the sound often depends upon the amount of turbulence generated at the leak site. The greater the turbulence, the louder the signal, the less the turbulence, the lower the intensity of the signal. When a leak rate is so low that it produces little, if any turbulence that i[...]

The Tone Test incorporates two basic components: a TONE GENERATOR (an ultrasonic transmitter) , and the Scanning Module in the Ultraprobe. To conduct the test: 1. Make certain the test item has no fluids or contaminants such as water, mud, sludge, etc., that can block the path of the transmitted ultrasound. -7- 2. Place the Tone Generator within th[...]

2. ELECTRIC ARC, CORONA, TRACKING DETECTION There are three basic electrical problems that are detected with the Ultraprobe 500: Arcing: An arc occurs when electricity flows through space. Lightning is a good example. Corona: When voltage on an electrical conductor, such as an antenna or high voltage transmission line exceeds the threshold value, t[...]

3. DETECTING BEARING WEAR Ultrasonic inspection and monitoring of bearings is by far the most reliable method for detecting incipient bearing failure. The ultrasonic warning appears prior to a rise in temperature or an increase in low frequency vibration levels. Ultrasonic inspection of bearings is useful in recognizing: a. The beginning of fatigue[...]

DETECTING BEARING FAILURE COMPARATIVE TESTING. The comparative method involves testing two or more similar bearings and "com- paring" potential differences. FOR COMPARATIVE TEST 1. Use contact (stethoscope) module. 2. Select a "test spot" on the bearing housing. Touch that spot with the contact module. In ultrasonic sensing, the[...]

5. LOCATING FAULTY STEAM TRAPS An ultrasonic test of steam traps is a positive test. The main advantage to ultrasonic testing is that it isolates the area being tested by eliminating confusing background noises. A user can quickly adjust to recognizing differences among various steam traps, of which there are three basic types: mechanical, thermost[...]

THERMOSTATIC TRAPS (bellows & bimetallic) operate on a difference in temperature between condensate and steam. They build up condensate so that the temperature of condensate drops down to a certain level below saturation temperature in order for the trap to open. By backing up condensate, the trap will tend to modulate open or closed depending [...]

6. LOCATING FAULTY VALVES Utilizing the contact (stethoscope) module in the Ultraprobe, valves can easily be monitored to determine if a valve is operating properly. As a liquid or gas flows through a pipe, there is little or no turbulence generated except at bends or obstacles. In the case of a leaking valve, the escaping liquid or gas will move f[...]

ULTRASOUND TECHNOLOGY The technology of ultrasound is concerned with sound waves that occur above human perception. The average threshold of human perception is 16,500 Hertz. Although the highest sounds some humans are capable of hearing is 21,000 Hertz, ultrasound technology is usually concerned with frequencies from 20,000 Hertz and up. Another w[...]
