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 approximately 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.

AI Overview BETA

Evident delay line transducers are single-element contact probes designed to work with replaceable delay lines for ultrasonic inspection. Their heavily damped element works with the delay line to improve near-surface resolution, helping reveal features close to a material’s surface. For inspecting adjacent turbine blades, permanent delay line models have a swivel head for tight access areas.

Frequency options span 2.25–20 MHz
Replaceable delay line transducers include a standard delay line and retaining ring
High-temperature and dry-couple delay lines are available
Sonopen models offer straight, right-angle and 45° handles
Harisonic Pencil typical range: approximately 0.010–0.250 inches in steel
