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.
|Thickness Gage Model||Transducer Frequency Range|
|2.0 to 30 MHz|
|0.5 to 5.0 MHz|
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.

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 for use up to 350° F (175° C)
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.

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.
|Delay Line Part Number||Maximum Thickness
*Exact range depends on material sound velocity, transducer frequency, part geometry and surface condition.
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.

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.

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.

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.
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.
