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.

*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.

Immersion transducers

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.

Test blocks and cables

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.
