Twin Compression Transducers

Protective Membrane (CDF)

Features

	Medium damped, 0º, twin lead zirconate elements providing low noise with high gain.
	Replaceable protective membrane improves contact on rough surfaces and maximises transducer service life.
	Rugged stainless steel case, specially designed for fatigue free handling, providing firm grip and stability during hand scanning.
	All the advantages of a combined double transducer, with increased wear resistance and longer useful life.

Frquency Spectrum and Signal Waveform

Frequent Applications

Used with or without the protective membrane for thickness gauging and near surface flaw detection on: plate, bar, tube & pipe, castings & forgings.
