  • Page 3 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. PISTOL HOUSING The main component of the Ultraprobe is its' pistol housing. From back to front, let's examine each part. A.

  • Page 4: Scanning Module

    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.

    4. HEADSET This heavy duty headset is designed to block out intense sounds often found in industrial environments so that the user may easily hear the sounds received by the ULTRAPROBE. To use, simply plug the headset cord into the headset jack on the metered pistol housing, and place the headphones over your ears.

  • Page 6: Ultraprobe Applications

    ULTRAPROBE APPLICATIONS 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 going from a pressurized laminar flow to low pressure turbulent flow.

  • Page 7: To Confirm A Leak

    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.
  • Page 8 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.
  • Page 9 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.

  • Page 10: Electric Arc, Corona, Tracking Detection

    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, the air around it begins to ionize to form a blue or purple glow.
  • Page 11 bearing shot 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.
  • Page 12 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 more mediums or materials ultrasound has to travel through, the less accurate the reading will be.

  • Page 13: Locating Faulty Steam Traps

    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, thermostatic and thermodynamic.
  • Page 14 -12- INVERTED BUCKET TRAPS normally fail in the open position because the trap loses its prime. This condition means a complete blow-through, not a partial loss. The trap will no longer operate intermittently. Aside from a continuous rushing sound, another clue for steam blow-through is the sound of the bucket clanging against the side of the trap.

  • Page 15: Locating Faulty Valves

    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.

  • Page 16: Ultrasound Technology

    -14- 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.

  • Page 18: Safety Precaution

    SAFETY ADVISORY PLEASE READ BEFORE USING YOUR INSTRUMENT. WARNING Improper use of your ultrasonic detector may result in death or serious injury. Observe all safety precautions. Do not attempt to make any repairs or adjustments while the equipment is operating. Be sure to turn off and LOCK OUT all electrical and mechanical sources before performing any corrective maintenance.
