NTS Ultrasonics has developed the RL-120 ultrasonic wheel probe intended for general purpose applications requiring a single ultrasonic transducer in a wheel.
The 120mm wheel accepts an off-the-shelf 12mm element immersion style ultrasonic transducer and achieves an internal water path length of 85mm.
Accessories for the wheel probe include an internal beam collimator which increases sensitivity, and a manual scanner.
The tyre is made from a rubber with lower ultrasonic attenuation than polyurethane at 5MHz, and which provides a softer, more complaint contact zone to the work piece. A key advantage of this ultrasonic wheel probe is the compact size compared to the water path length.
Current uses for the RL-120 ultrasonic wheel probe include inspection of rubber products in Australia and an application in a steel mill in the US. Potential applications include conveyor belt inspection, corrosion mapping, thickness testing and flaw detection.
NTS Ultrasonics can also supply smaller and larger diameter ultrasonic wheel probes.
