The SW Series of 15 and 20MHz transducers is intended for precise and repeatable inspection and evaluation of spot welds in bonded metal sheets.

SW Series transducers have outstanding signal resolution, with the controlled water column allowing distinct separation of intermediate echoes for evaluation purposes at less than 0.5mm (0.020”) from the entry surface. High-sensitivity piezoelectric elements provide ultrasonic beam penetration into thick metal sheets.

Each transducer is supplied with a comprehensive inspection report, certifying that the transducer complies with strict tolerance limits on the ultrasonic properties of relevance for spot weld inspection.
