Krautkrämer ultrasonic transducers For flaw detection and sizing

Our core ability is to match ultrasonic probes to the inspection applications of today, both simple and complex. This skill lets allows us to design and manufacture fine-tuned quality probes that meet your customer-specific requirements. We build quality into every step we perform—from start to finish: • Requirement analysis At the very beginning of our discussions with you, we draw on our experience manufacturing more than 1 million probes—including 14,000 probe variations—to build quality into our requirement analysis process. • Specifications. To help ensure quality results, each product...

Transducer selection criteria and performance General information The ultrasonic transducers in this catalog are divided into two general categories, Contact and Immersion. Transducers for the contact inspection method Straight beam—single element • arts with regular geometry and P relatively smooth contact surface • Flat or curved contact surface • law or backwall parallel to F surface or detectable with beam normal to surface • referred for penetration of P thick sections • elay line types improve near D surface resolution • equires couplant layer, typically a R gel, oil, or paste •...

Transducer selection criteria— European standards For transducers manufactured to European standards, technical and performance information is provided throughout this catalog based on the definitions below. A comprehensive data sheet is supplied with most flaw detection transducers at no charge. Description Explanation Diameter D or length x width a x b of the transducer element. The size of the element strongly affects the shape Element size D or a x b of the transmitted sound field. Slight deviations, (e.g., imperfect shape or positions with reduced radiation due

Transducer selection criteria— North American standards For transducers manufactured to North American standards, Baker Hughes Inspection Technologies offers three performance ranges: Alpha, Benchmark, and Gamma Series. Waveform and frequency certification, per ASTM E-1065, are supplied with all flaw detection transducers at no charge. Alpha series features Real time Gamma series features • Recommended for applications where resolution is the primary consideration. • Suitable for applications such as thickness measurement and near-surface flaw detection. • Very short pulse—mechanically...

Contact transducers Straight beam contact transducers, protective face General purpose, larger parts with simple geometry Forgings, billets Plates, bars, square profiles Containers, machine components, shells Inspection at high temperature with delay line European models have replaceable membrane: – Improves coupling on uneven or curved surface – Extends transducer life. – Suitable for DGS flaw sizing method – High temperature delay lines also available – Lemo 1 (B..S) or Lemo 00 (MB..S) connector, side mount standard, top mount optional North American models can be used with three types of...
