Ultrasound Testing (Ut) is a key element in a successful Asset Condition Management program. At a relatively insignificant capital entry cost, the benefits to reliability and operating cost savings produced by this technology can be truly enormous.

The SDT270 can quickly and easily detect air and steam leaks for huge energy savings and greater capacity. Another application for the SDT270 is bearing condition monitoring, particularly lubrication. The SDT270 lets you pinpoint precisely when the optimal lubrication state of a bearing has been achieved while lubricating it, thereby preventing premature wear, friction, heat and efficiency losses.

Dangerous electrical faults such as arcing tracking and corona can also be easily (and safely!) detected with the SDT270.

The upgradeable SDT270 platform with its ULTRANALYSIS® SUITE (UAS) software can grow with your needs and help you reap the benefits of ultrasound technology in your reliability program.
