SG-2 Sound


Ultrasonic Sound Generator


Monarch Ultrasonic Tone

Battery-powered continuous tone source
of 40 kHz. Capable of 155 dB at 30 cm
and can transmit up to 40 feet.
Ideal for enclosed vessels/tanks.

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.

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.

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.
