Panametrics-NDT Ultrasonic Transducers

An immersion transducer is a single element longitudinal wave transducer with a 1/4 wavelength layer acoustically matched to water. It is specifically designed to transmit ultrasound in applications where the test part is partially or wholly immersed.

Advantages:

• The immersion technique provides a means of uniform coupling
• Quarter wavelength matching layer increases sound energy output
• Corrosion resistant 303 stainless steel case with chrome-plated brass connectors
• Proprietary RF shielding for improved signal-to-noise characteristics in critical applications
• All immersion transducers, except paintbrush, can be focused spherically (spot) or cylindrically (line) (see Technical Notes page 45)
• Customer specified focal length concentrates the sound beam to increase sensitivity to small reflectors

Applications:

• Automated scanning
• On-line thickness gaging
• High speed flaw detection in pipe, bar, tube, plate, and other similar components
• Time-of-flight and amplitude based imaging
• Through transmission testing
• Material analysis and velocity measurements

Usage Note: Transducers should not be submerged for periods exceeding 8 hours. Allow 16 hours of dry time to ensure the life of the unit.

Standard Case

• Knurled case with Straight UHF connect or (SU)
• Contact us for nonknurled case design and availability of other connector styles
• Frequencies ranging from 1.0 to 25 Mhz

*Please select a specific focus between min max.
**If a focus is required, select a focal length between min max

Large Diameter Case

• Large element diameters increase near field length allowing for longer focal lengths
• Larger diameters can increase scanning index
• Low frequency, large element diameter designs available for challenging applications

*Please select a specific focus between min max.
**If a focus is required, select a focal length between min max

Slim Line Case

• Stainless steel case is only 0.38" (10 mm) in diameter, ideal for limited access areas
• Standard configuration is Straight and fits Microdot ®connector style
  

*Please select a specific focus between min max.
**If a focus is required, select a focal length between min max

Pencil Case

• Small diameter, 2" (51 mm) long barrel improves access to difficult-to-reach areas
• Standard connector style is Straight UHF (SU)
  

*Please select a specific focus between min max.
**If a focus is required, select a focal length between min max

Side Looking Immersion Transducers

• Ideal for measuring wall thicknesses of pipe where access to the outer diameter is limited
• Small outer diameter allows for greater accessibility in tight spaces than standard immersion transducers with reflector mirrors
• Sound exit point is located at a 90° angle relative to the straight Microdot ®connector
• Probe extensions such as the F211 are available to lengthen the standard design
  

Note: All above side looking immersion transducers have straight Microdot connectors.

Extra Miniature (XMS) Transducer

The XMS transducer is an extremely small 10 MHz immersion transducer with a 3 mm (0.118") diameter by 3 mm (0.118") long case. This transducer is ideal for extremely tight access areas or for multi-element array flaw detection. The transducer assembly has a special connector attached to the 1 m (38") long potted cable. An adaptor is also available to interface with most commercial ultrasonic equipment.

Accuscan Paintbrush

• Large scanning index is ideal for inspections of aluminum or steel plate
• Sensitivity uniformity of better than ±1.5 dB is maintained across the transducer face (sensitivity peaks at the edges are also controlled)

For 7.5 MHz and 10 MHz, case height (A) is 0.62"

Reflector Mirrors

• Directs sound beam when a straight-on inspection is not possible
• Standard mirrors provide a 90Ã?° reflection of the sound beam

Note: Contact us for other reflected angles.

Immersion Search Tubes

• Provides a quick and easy way to fixture and manipulate immersion transducers

Bubblers

• Allows for immersion testing when complete immersion of parts is not desirable or possible
• Designed to maintain a consistent, low volume flow of water

RBS-1 Immersion Tank

RBS-1 immersion tank is designed to simplify testing measurements using immersion techniques. It consists of a clear acrylic tank, a submersible pump and a transducer fixture in a single, portable unit. The pump feeds an adjustable stream of water to a bubbler mounted in the fixture, providing a water column to couple sound from an immersion transducer into the test piece. 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.

Clear Acrylic Tank

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

Pump

• Up to 0.25 gallons (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)

Handheld 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. The V316B and bubbler combination can resolve thicknesses down to 0.008" (0.2 mm).
