Ultrasonic Leak Detection |
 |
 |
How does it Work...
Ultrasound works by detecting the high frequency sound associated with friction, arcing and turbulence in industrial systems. These sounds are translated/converted down to the audible range where they can be heard in the headset and viewed on the meter. Translation is done by heterodyning --comparing the incoming signal with one generated by the meter. Our meters are most sensitive to sounds around 40 kHz, that's twice the frequency of the best human hearing. Because we focus on a specific band of sound... wind noise, industrial noises, voices, traffic, and most normal operational sounds will NOT be detected. You can actually yell directly into the sensor and hear nothing. This exact frequency focus allows for precise leak detection and bearing defect discovery. |

| Applications | Air Leaks- Gases- Fluids
Do your compressors run on the weekends when the plant is unoccupied? Do you have difficulty maintaining optimum pressures? Have you come to rely on your backup compressor for routine demand? Still think Air is Free??? Save thousands in energy costs by repairing air leaks. Also detects Freon, Propane and all gas leaks. | 
testing for air leaks with the SG-2
sound generator and VPE 1000
| Steam Traps & Valves- All Fluid Valves
A major source of energy loss is through leaking steam traps and valves. Leaking steam traps are tremendously inefficient ... it's like trying to heat your house with the windows open. And bad steam traps are surprisingly common, roughly 30% of the traps in a plant with no trap testing programs will be leaking! Use the contact probe to quickly hear internal flow through steam traps and valves. |  
testing steam traps is simple | Rolling Element Bearings
Using ultrasound to identify bearing wear in its early stages can be a valuable tool toward avoiding major downtime. As internal components in moving machinery begin to wear, increased friction creates subtle changes in the ultrasonic sound being generated. These changes in ultrasound present themselves before other signs like heat or vibration are noticeable. |  advanced warning of
