Protected Face Transducers | Evident Australia

1/2

A protected face transducer is a single element longitudinal wave contact transducer that can be used with either a delay line, protective membrane, or protective wear cap.

High temperature inspections

Receive 1-3 days from order

Advantages:

Provides versatility by offering removable delay line, protective wear cap, and protective membrane
When the transducer is used alone (without any of the options), the epoxy wear face provides good acoustic impedance matching into plastics, many composites, and other low impedance materials
Cases are threaded for easy attachment to the delay line, protective membrane, and wear cap options

Applications:

Straight beam flaw detection
Thickness gaging
High temperature inspections
Inspection of plates, billets, bars, and forgings

Standard Protected Face

Comfort Fit sleeves are designed to be easily held and provide steady grip while wearing gloves
Standard connector style Right Angle BNC (RB), may be available in Straight BNC (SB)
Delay line, protective membrane, and wear cap options sold separately from the transducer

High Temperature Delay Line Options

Allows for intermittent contact with hot surfaces*
Improves near surface resolution
Contouring of delay lines provides better coupling on curved surfaces
Warm temperature delay lines (WTD) can be used for room temperature applications

*Recommended usage cycle is ten seconds maximum contact followed by one minute of air cooling. However, the transducer itself should not be heated above 122°F (50°C).

X = standard delay line lengths, available in 1/2" (13 mm), 1" (25 mm), 1-1/2" (38 mm). Specify at time of ordering.

Note: For the delay lines above, a room temperature material longitudinal wave velocity of 0.100 in/µsec ±0.005 in/µsec may be used as an approximation for basic calculations. This value should not be used for engineering design calculations.

Protective Membrane Option

Improves coupling on rough or uneven surfaces
Dry couple to smooth, clean surfaces

*Available in 36" x 36" x 1/32" sheets. Order part number NPD-665-3101.

† Kit includes 12 Membranes, 1 ring, C-2 couplant

Protective Wear Cap Option

• The nylon wear cap provides an economical solution in applications requiring scanning or scrubbing of rough surfaces

AI Overview BETA

Evident’s protected face transducers are single-element longitudinal-wave contact transducers for inspecting materials. Their threaded cases take removable delay lines, protective membranes or wear caps, letting the contact setup suit different inspection conditions. For straight-beam flaw detection and thickness gauging, the Comfort Fit sleeve is designed to give a steady grip when held with gloves during inspection.

Epoxy face matches acoustic impedance for plastics, many composites and other low-impedance materials
High-temperature delay lines: maximum 10 seconds’ contact, then one minute air cooling
The transducer itself should not be heated above 122°F (50°C)
Protective membranes improve coupling on rough or uneven surfaces
Nylon wear cap is intended for scanning or scrubbing rough surfaces
