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.

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.
