SDT Ultrasound Detectors

Ultrasound detectors can hear the trouble spots you can't.

Ultrasound detectors convert and step down sounds that exist above the range of human hearing.

If you can hear the sound, then an ultrasonic detector is deaf.

But if the sound is occurring above human hearing, then our SDT unit will be singing out loud. You now have the ability to hear more of what is really going on in your facility.

Many different warning signals give off ultrasonic sound. In the airborne environment, leaks of compressed gas or air can generate significant ultrasonic sound. Even if your plant is so loud you have a hard time yelling to each other, you will be amazed at how the SDT ultrasound detector eliminates all of the background noise to hone in on your problem.

Choose your platform and performance. You can always upgrade later. One box has it all, no need to buy a new box should your needs expand. SDT Ultrasound and Ultrasonic Detectors by Failure Prevention Associates, Inc.

For example, at a waste water facility, in the basement, below a massive blower the audible sound was so loud no amount of yelling could be heard. You had to read a man's lips and gesture to understand each other. But the SDT ultrasound detector heard only a single whistle coming from a blown seal on a regulator.

Repairing that one large leak took away the need for 1 of the 3 new compressors that had recently been installed.

If only they had performed an air leak survey before ordering the compressors.

If you have leaks you can hear, then there are many more leaks that just aren't big enough to make an audible sound. If you don't hear leaks, but your compressors run when demand is off peak. Then you have leaks.

Electrical arcing, tracking and corona generate ultrasonic sound immediately. You do not have to wait for the condition to worsen so excess heat brings a thermal difference that an IR camera can pick up.

Using contact probes or magnet sensors, you can perform structure borne ultrasound detection. This is used extensively for monitoring bearing conditions, traps, valves and to perform acoustic lubrication for proper grease application.

The primary use of contact probe is for obtaining mechanical function information. But the uses extend beyond bearings to include steam traps, pneumatics, and much more.
