Sonus XT

The Compact Ultrasonic Testing Device for Preventive Maintenance

Overview Image


The versatility of Sonus XT makes it ideally suited to work with any plant maintenance program and the perfect complement to other Predictive Maintenance (PDM) Technology. Ultrasound detection can be utilized to detect early warning signs of equipment failure and to conduct energy conservation audits. Quickly and Safely perform closed panel airborne Ultrasound inspections of electrical equipment including Switchgear, Switchboards, Panelboards, Transformers, Motor Control Centers and Process Equipment Panels to detect early warning signs including such as Arcing, Tracking and Corona. Fast and accurate diagnosis of problems using the Sonus XT will save you time and money.

Small, Compact and Powerful Hand-held Ultrasound Unit

The Sonus XT units provide exceptional portability in compact lightweight sizes that are as powerful as the other larger units on the market. A smaller sized unit allows the inspector to perform a full day of inspection without struggling to carry around a big bulky unit all day.

An Unparalleled Versatility

From the detection of Corona, Treeing(Tracking), Arcing in the Electrical domain to Inner or Outer Race faults in motors bearings, Sonus XT units can do so many things for your maintenance program. Leak surveys can quickly identify annual losses and improve the efficiency of your compressed air systems. You can also perform an energy audit on your steam systems and improve the overall efficiency while reducing the operational costs at your site.

Ease of Use With a Minimal Learning Curve

The Sonus XT units require a minimal amount of training to get a program up and running inspecting your critical assets. Easily transition from an Electrical Inspection to a Motor Bearing Inspection by swapping the airborne probe for the contact probe without any complicated menu setting adjustments.


Battery Operated

Reduce downtime between inspections since the unit is powered by AA Batteries. Quickly and easily carry on an inspection without having to carry heavy batteries that take hours to charge and can stop an inspection in its track.

Easily Interchangeable Probes

With a wide array of probes that can easily be interchanged quickly, the inspector has the flexibility to perform multiple applications: from Transmission Line testing using the Parabolic Dish with Walther Laser Sight to the Contact Module for testing Valves, Steam Traps, Gear Boxes, and Bearings. Using a robust four pin locking probe connection design, there is no need to worry about damaging the probe connections.

Compatible With All IRISS PDS and VPDS Ports

Perform ultrasound electrical inspections with more accuracy than scanning a seam of a cabinet by having direct access into the cabinet interior. PDS and VPDS ports allow the Sonus XT to safely scan from the outside of the cabinet and not lose any of the signal due to diffraction.

Great For Energy Conservation Programs

The SONUS XT is a great tool and inexpensive unit that can save considerable time and money for an Energy Conservation program. Detection of leaks and fixing compressed air inefficienies can often reduce energy costs by up to 30%.
