Contact ultrasonic transducer BBTM-CW

contact ultrasonicdirect-contactmeasurement

Product Overview
The BBTM-CW is a contact ultrasonic probe for measurement of corrosion, erosion and remaining-wall thickness on pipes, storage tanks, pressure vessels, industrial equipment and small mechanical components. It is intended for industrial maintenance, condition assessment and periodic inspection, including measurements on rough surfaces, curved components and near-surface regions.

Key Features

• Contact ultrasonic transmit–receive probe for corrosion and remaining-wall thickness
• Separate transmit and receive acoustic paths for improved near-surface response
• Selectable frequencies within 1–10 MHz and multiple element shapes and sizes
• Contact face available flat or contoured to match curved components
• Good coupling adaptability on rough or coarse-grained surfaces
• Configurations available in standard, compact and small sizes for restricted access

Typical Applications

• Pipe corrosion and remaining-wall thickness measurement
• Storage tank and pressure vessel wall inspection
• Erosion monitoring on industrial equipment
• Measurements on curved or rough-surfaced components
• Cladding and weld-overlay inspection
• Inspection of screws, bolts, pins and other small components
• Contact ultrasonic inspection of coarse-grained materials
