The SLF is a single normal beam compression wave contact transducer designed with replaceable face attachments for flexible ultrasonic testing applications. Medium damped for general-purpose flaw detection and thickness measurement, it can be fitted with polymer membranes for rough surface protection or delay line attachments for high-temperature testing.

Key Features & Advantages
Single Normal Beam Design: Engineered for standard straight-beam compression wave contact inspection.
Medium Damping: Provides an optimal balance between pulse resolution and penetration depth for general use.
Replaceable Face Attachments: Supports polymer membrane protection for “soft nose” applications on rough surfaces, as well as delay line attachments of varying lengths.
High-Temperature Performance: Standard operating capability up to 50°C (120°F), with high-temperature delay line options suitable for temperatures up to 400°C.
Composite Variants: Circular, lead metaniobate crystal composite options are available under the PSLF transducer range.
Common Applications
Evaluation of castings and forgings
Testing of white metal bearings
High-temperature component and pipeline inspection
