Product Information

Dual Element Transducers are for general flaw detection and thickness gauging on materials with irregular or pitted surfaces. The ADP and RC models are color coded for quick frequency identification.

The low profile ADP model has a potted BNC cable.

The RC Dual models have a 4-pin LEMO connector which allows for quick and easy cable replacement.

All FDU models have mini Microdot threaded connectors.

All models may be contoured to fit ID and OD curvatures.

• Remaining wall thickness, corrosion, erosion
• Near surface flaw detection
• Small parts—screws, bolts, pins
• Cladding and weld overlay
• Bond testing
• Railroad wheels
• Core flaws in shafts, bars, billets
• Coarse grain materials
