Precision Thickness Gauges

Olympus NDT offers a complete selection of transducers, cables, couplants, calibration test blocks, and accessories to meet a wide variety of ultrasonic precision thickness gaging applications.

The Panametrics-NDT Microscan transducers are frequently used with the Series 25 and Series 35 thickness gages, as well as other commercially available thickness gages, flaw detectors and ultrasonic instrumentation.

Microscan transducer part numbers reflect the connector designation:
RM = Right Angle Microdot ^®,
SM = Straight Microdot,
RB = Right Angle BNC,
SB = Straight BNC,
SU = Straight UHF

When selecting a transducer, please review the chart below or consult the Transducer Frequency Range in the Instruction Manual that was shipped with your gage.

Contact Transducers

One of the advantages of a Panametrics-NDT Microscan contact transducer is its versatility; a single transducer can cover a broad thickness range in many engineering materials. Contact transducers are constructed with the unique WC-5 wearplate for greater durability and a longer life.

SONOPEN ^® Transducers

The Sonopen ^® transducer has a replaceable delay line that is tapered to a small contact area. This transducer makes reliable thickness measurements in applications such as turbine blades, threads on plastic bottle necks and tight radii on plastic containers. High-temperature Sonopen delay lines are also available.

Delay Line Transducers

Panametrics-NDT Microscan delay line transducers provide excellent performance on very thin materials, elevated temperatures or in applications that require a high degree of thickness resolution.

Replaceable Delay Lines

Standard Delay Lines
Standard delay lines are used in many applications. Special conditions such as high surface temperature, curvature of the material or hard-to-access areas may require the use of special delay lines.

High temperature delay lines
High temperature delay lines function as a protective buffer between the hot surface of the test piece and the transducer's crystal. At elevated temperatures, intermittent contact is recommended to protect the transducer from thermal damage.

Immersion Transducers

Panametrics-NDT Microscan immersion transducers are designed to transmit and receive ultrasound in water. Thickness measurements by immersion technique are often preferred when the test piece has a complex geometry or in online applications. Typical offline applications include wall thickness measurements on small diameter plastic or metal tubing, scanned or rotary measurements and thickness measurements on sharply curved parts. Transducer focusing may be necessary depending on the application.

Bubblers

We offer bubblers for easy implementation of immersion testing. They act as a holder for the transducers to maintain consistent water flow from transducer to test surface, and prevent the accumulation of air bubbles on the transducer face.

Bubbler Transducer Assembly

Handheld bubbler transducers are available in either 20 MHz (V316B) or 10 MHz (V312B). They are immersion transducers that screw onto a bubbler assembly (B120), which has a replaceable stainless steel tip and a water feed tube. They offer high resolution and easy access inspection of thin materials.

RBS-1 Immersion Tank

Panametrics-NDT RBS-1 immersion tank is designed to simplify ultrasonic thickness measurements using immersion techniques. It consists of a clear acrylic tank, a submersible pump and a transducer fixture in a single, portable unit. It is ideal for offline thickness measurements on metal, glass and plastic products such as small containers, pipe or tubing, sheets or plates or machined parts.

Tank

• 5.5 x 12 x 8 in (140 x 305 x 200 mm)
• 0.83 gallon (3.1 liter) capacity

Pump

• 0 to 0.25 gallons (0 to 0.9 liters) per minute
• 115 or 230 V, 30 Watt (voltage range 90 to 135 VAC), 50 to 60 Hz
• Submersible (ground fault interrupter circuit recommended)

Couplants

The use of couplant is almost always necessary to provide acoustic coupling between the transducer and the test piece. We offer various types of couplants to suit virtually all applications.

Calibration Test Blocks

Test blocks are necessary for the calibration of ultrasonic thickness gages and should be used to maintain and verify the accuracy, dependability and reliability of ultrasonic measurements. Blocks are held to tighter tolerances than called out in ASTM E797 code. Metric test blocks are available.

Transducer Cables

Olympus-NDT offers a wide selection of transducer cables suitable for all ultrasonic thickness gaging instrumentation.
