Home/ Products/ Transducers and Probes/ Single and Dual Element Transducers / Protected Face

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.

Overview

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
