Locate costly leaks in your compressed air system!

What is the Ultrasonic Leak Detector?

The Ultrasonic Leak Detector (ULD) is a superior instrument with high quality that can locate costly leaks in a compressed air system. The Ultrasonic Leak Detector is compact, lightweight & designed for one hand operation. Using the Ultrasonic Leak Detector a person need only aim it in the direction of a suspected leak. The LED display will light & an audible tone can be heard with the use of the headphones, when a leak is detected. At distances up to 20’ (6.1m) away the testing of various unions, pipes, valves & fittings can be done quickly & effectively.

Why the Ultrasonic Leak Detector?

 

ULD detects the ultrasonic noise created by pressure or vacuum leaks of any gas, regardless of type: CFC's, HFC's, Nitrogen, CO2, Steam, etc.By using a technique called “heterodyning” it translates the ultrasound to a lower frequency which our ears can interpret.

This detection method often use a microphone technology; which detect outdoor leaks by sensing the distinct high frequency ultrasound emitted by all highpressure gas leaks, meaning that the gas does not have to reach the sensor – just the sound of the gas leak. Plants easily waste up to 30% of the compressor output through leaks that go undetected .The overall operating costs can be reduced by saving the wasted compressed air.

What is Ultrasound?


uld1 Vivek Engineers - Ultrasonic Leak DetectorUltrasonic sound is a range of sound that is above human hearing capacity. Most people can hear frequencies from 20 Hz to 20 kHz. Sound from 20 kHz to 100 kHz can not be heard and is called “ultrasonic”. The Model 9061 Ultrasonic Leak Detector converts ultrasonic sound emissions to a range that is audible to people. (The sound generated by the ULD is 32 times lower in frequency than the sound that is received.)


Applications

  • Locates leaks in air, steam and non-flammable gas systems including pipes, fittings, valves, cylinders and pressure vessels
  • Finds the source of bearing and gear wear
  • Locates arcing in an electrical system
  • Detects refrigeration and air conditioning system leaks
  • Locates leaks in brake systems, tubes, tires and radiators
  • Senses cracks in moving rubber v-belts
  • Detects leaks in vacuum systems
  • Check condition of engine seals

Advantages

  • Detects any pressurized air leak up to 20 feet (6.1m) away
  • Converts ultrasound to an audible frequency
  • LED display confirms the leak location
  • Detects leaks in noisy industrial environments
  • Sensitivity controls provide accurate detection
  • Not affected by contaminants or windy conditions
  • Rugged carrying case
  • Meets ASTM standards

In a plant where loud noise levels exist, it is very difficult to locate leaks by merely listening for them. Most plant noises are in the normal audible range of human hearing, while air escaping from a small orifice is ultrasonic. The ULD can be adjusted to filter out background noise using the three sensitivity settings of X1, X10 and X100 along with an “on/off” thumb wheel for fine sensitivity adjustment. The ultrasonic_2 Vivek Engineers - Ultrasonic Leak Detectorparabola or tubular extension (shown below) can also be attached to the ULD to mask out intense background noise. The ULD detects only the ultrasonic sounds that are generated.

Ultrasound is directional in transmission and is loudest at the source. Turbulence created by the air forced through a small orifice generates ultrasonic sound. This emitted sound is called “white noise” and occurs when the air moves from a high pressure area such as a pipe or vessel and escapes to a low pressure area such as the room. The Ultrasonic Leak Detector converts the turbulent flow to a frequency that can be heard using the headphones. As the ULD moves closer to the leak, more LEDs on the display light to confirm the source of the leak.

The Model 9061 Ultrasonic Leak Detector quickly pinpoints a costly leaks in a noisy,industrial environment.

In some cases, the suspected leak is in a hot area and/or close to moving parts. The tubular extension and parabola make it possible to probe these difficult locations from a distance to isolate the leak.

Find One Leak - Pay For Your Ultrasonic Leak Detector

Consider one small leak that is equivalent to a 1/16” diameter hole. At 80 PSIG, it consumes 3.8 SCFM (Standard Cubic Feet per Minute) or 108 SLPM (Standard Liters Per Minute).

Most large plants know their air cost. If you don’t know your actual cost per 1000 SCF (Standard Cubic Feet), a reasonable average is $0.25 per 1000 SCF (28,329 Standard Liters).

Dollars consumed per hour = SCFM consumed x 60 minutes x cost/1000 SCF
= 3.8 x 60 x 0.25/1000
= $0.06 per hour
= $1.37 per 24 hour period
= $9.58 per week
= $497.95 per year

 

The Model 9061 Ultrasonic Leak Detector comes complete
with a hard-shell plastic case, headphones, parabola,
tubular adaptor, tubular extension and 9 volt battery.
