Ultrasound Accessories

CTRL designs and manufactures attachments to enhance the capabilities of the UL101 for a variety of applications.

PowerBeam 300

The PowerBeam 300 is a parabolic accessory originally designed to test high voltage insulators and transformers from a safe distance with a high degree of accuracy. The PowerBeam 300 can accurately pinpoint sources of ultrasound within 1 degree off target from up to 300 feet (91.44 meters) away.

The PowerBeam 300 accurately pinpoints source of ultrasound to within 1 degree from center and improves the sensitivity of the UL101. The "PB300" was originally designed for the indication and location of corona discharge and arcing on medium/high voltage transformers.

The PB300's ability to pinpoint ultrasound is very useful when finding compressed air/gas or steam leaks in pipes located on high ceilings. There is no need to get a ladder or scissor lift.

CTRL PowerBeam 300 Parabolic Accessory
  • Energy Savings

  • Safety

  • Corona Discharge

  • Electrical Arcing & Tracking to Prevent Arc Flash

  • Time Savings

  • Cost Savings vs. Corona Camera


Find leaks from further away and pinpoint to exact source without use of a scissor lift.

Electrical Inspection 
(partial discharge)

Arcing - indication that a failure has occurred

Tracking - detectable even when infrared cannot

Detect leaks and operation from a safe distance.

Power Transmission 
(switch gear, transformers, etc)

Corona discharge is a major contributor to energy loss and also Radio Frequency Interference
