Advantages:

• Heavily damped transducer combined with the use of a delay line provides excellent near surface resolution
• Higher transducer frequency improves resolution
• Improves the ability to measure thin materials or find small flaws while using the direct contact method
• Contouring available to fit curved parts

Applications:

• Precision thickness gaging
• Straight beam flaw detection
• Inspection of parts with limited contact areas
• Replaceable Delay Line Transducers
• Each transducer comes with a standard delay line and retaining ring
• High temperature and dry couple delay lines are available
• Requires couplant between transducer and delay line tip

Harisonic Pencil Transducers

These high frequency, focused delay line transducers are compatible with any ultrasonic instrument capable of displaying a return echo at depths as low as .010 inches in steel. The typical range is approximay from .010 inches to 0.250 inches in steel. The 0.060 inches circular contact face enables readings to be taken on curved surfaces. Typical applications for these transducers include the inspection of turbine blades, small diameter tubing and concave areas in small parts. Both transducers utilize replaceable delay tips. For best performance, a short cable (such as MB type, 6') should be used. These models, indicated by a part number ending with an "L", incorporate PowerLink™ Technology to assure optimal performance when used with a Sonic ultrasonic instrument. 

The HC-876 ultrasonic transducer operates at high frequency (20 MHz) with a broad bandwidth and small contact surface. Its chief application is thickness measuring of critical components such as jet engine blades. It is fitted with a Microdot connector.
