Page 7: Trigger Switch (E)
Version 1 Trigger Switch (E) The Ultraprobe is always "off' until the trigger switch is pressed. To operate, simply press the trigger; to turn the instrument off, release the trigger. Frequency Adjust Dial (F) There are numbers ranging from 100 kHz down to 20 kHz. These represent the range of frequency selection capable with the Ultraprobe. -
Page 8: Trisonic™ Scanning Module
Version 1 Trisonic™ Scanning Module Trisonic Scanning Module This module is utilized to receive air-borne ultrasound such as the ultrasounds emitted by pressure leaks and electrical discharges. There are three prongs at the rear of the module. For placement, align the prongs with the three corresponding jacks in the front end of the metered pistol housing and plug in.The Trisonic Scanning Module has a phased array of three piezoelectric transducers to pick up the air-borne... -
Page 9: Contact (Stethoscope)Module
Version 1 Contact (Stethoscope)Module Stethoscope Module This is the module with the metal rod. This rod is utilized as a "waveguide" in that it is sensitive to ultrasound that is generated internally such as within a pipe, bearing housing, steam trap or wall. Once stimulated by ultrasound, it transfers the signal to a piezoelectric transducer located directly in the module housing. -

Page 12: Ultraprobe Applications
Version 1 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 (Fig. -
Page 13: How To Locate Leaks
Version 1 How to locate leaks 1. Use the TRISONIC SCANNING MODULE. 2. Select the LOG setting on the meter selection dial. 3. Use "fixed-band" position on the Frequency selection dial. If too much background noise is present, try some of the shielding methods listed below. 4. -
Page 14: Shielding Techniques
Version 1 Shielding Techniques Since ultrasound is a high frequency, short wave signal, it can usually be blocked or "shielded". NOTE: Men using any method, be sure to follow your plant's or company's safety guidelines. Some common techniques are: 1. Body: place your body between the test area and the competing sounds to act as a barrier 2. -
Page 15: Low Level Leaks
1. Build up the pressure (if possible) to create greater turbulence. 2. Utilize LIQUID LEAK AMPLIFIER. This patented method incorporates a UE Systems product called LIQUID LEAK AMPLIFIER, or LLA for short. LLA is a uniquely formulated liquid substance that has special chemical properties. -
Page 16: Electric Arc, Corona, Tracking Detection
Often referred to as "baby arcing", follows the path of damaged insulation. Although theoretically the Ultraprobe 2000 can be used in low, medium and high voltage systems, most of the applications tend to be in medium and high voltage systems. When electricity escapes in high voltage lines or when it "jumps"... -
Page 17: Monitoring Bearing Wear
Version 1 Monitoring 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. -
Page 18: Detecting Bearing Failure
Version 1 Detecting Bearing Failure There are two basic procedures of testing for bearing problems: COMPARATIVE AND HISTORICAL. The comparative method involves testing two or more similar bearings and "comparing" potential differences. Historical testing requires monitoring a specific bearing over a period of time to establish its history. -
Page 19: Attenuator Transfer Curve
Version 1 Attenuator Transfer Curve (SAMPLE DO NOT USE WITH YOUR INSTRUMENT) In order to use this method, refer to the ATTENUATOR TRANSFER CURVE which is supplied for each instrument There are two curves. Use the curve marked STETHOSCOPE MODULE. On the curve, the vertical axis numbers indicate various SENSITIVITY levels, while the horizontal axis displays DECIBELS. -
Page 20: Lack Of Lubrication
SLOW SPEED BEARINGS Monitoring slow speed bearings is possible with the Ultraprobe 2000. Due to the sensitivity range, it is quite possible to listen to the acoustic quality of bearings. In extremely slow bearings (less than 25 RPM), it is often necessary to disregard the meter and listen to the sound of the bearing. -
Page 21: General Mechanical Trouble Shooting
Version 1 Proper Lubrication Lack of Lubrication Increases amplitude levels Reduces Friction General Mechanical Trouble Shooting As operating equipment begins to fall due to component wear, breakage or misalignment , sonic and more importantly, ultrasonic shifts occur. The accompanying sound pattern changes can save time and guess work in diagnosing problems if they are adequately monitored. -
Page 22: Locating Faulty Steam Traps
Version 1 In gearboxes, before missing gear teeth may be detected as an abnormal click, the normal sounds of gears must be understood. In pumps, certain pumps will have surges which may confuse inexperienced operators by the constant shifting of the meter readings. The surge pattern must be observed before a lower, consistent meter reading can be recognized as the true meter reading. -
Page 23: General Steam/Condensate/Flash Steam Confirmation
Version 1 General Steam/Condensate/Flash Steam Confirmation In instances where it may be difficult to determine the sound of steam, flash steam or condensate, 1. touch at the immediate downstream side of the trap and reduce the sensitivity to get a mid-line reading on the meter ("50"). -
Page 24: Locating Faulty Valves
Version 1 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 25: Confirming Valve Leakage In Noisy Pipe Systems
Version 1 To do this: a. Touch upstream of the valve and gradually rotate Frequency Select Dial until the stray signals are minimized or until the desired fluid flow is heard clearly. b. Touch the upstream side, valve seat, downstream sides ( as described above) and compare differences. Confirming Valve Leakage in Noisy Pipe Systems Occasionally in high pressure systems, stray signals occur from valves that are close by or from pipes (or conduits) feeding into a common pipe that is near the downstream side of a valve. -
Page 26: Leakage Behind Walls
Version 1 Leakage Behind Walls 1. Look for water or steam markings such as discoloration, spots in wall or ceiling, etc. 2. If steam, feel for warm spots in wall or ceiling. 3. Test area using steps 1-3 as outlined on page 26, section "A", "Procedure". 4. -
Page 27: Ultrasound Technology
Version 1 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 way of stating 20,000 Hertz is 20 kHz, or KILOHERTZ. -
