Single Element Delay Line Pencil Transducers
High Precision and Accessibility for Specialised Applications
Checkline's single-element delay line pencil transducers are essential tools for precise thickness measurement of materials such as aluminium, titanium, steels and thin plastics. Optimised for use with the TI-PVX Ultrasonic Thickness Gauge, these probes are ideal for testing in hard-to-reach areas and for small-scale applications that demand accuracy.
Key Features:
- Precise Focus Point: Concentrates the ultrasonic beam into a 1/16" or 1/8" spot, enabling highly accurate measurements on containers, small-diameter pipes and turbine blades.
- Robust Construction: Each model is fitted with a 1/4" crystal and a microdot connector, ensuring secure connectivity and reliable mounting.
- Ergonomic Design: Available in configurations such as top-entry or right-angle for ease of use across different industrial applications.
Key Benefits:
- Application Flexibility: Offered in multiple variants, including T-481-5507 (10 MHz), T-681-4507 (10 MHz, 90° right-angle) and T-581-5507 (15 MHz), to meet specific testing requirements.
- High-Resolution Measurements: Delivers the precision required for critical thickness evaluations and defect detection across sensitive materials.
- Material Adaptability: Supplied with acrylic and graphite delay tips to enable accurate measurements on a wide range of plastics, compensating for different acoustic impedances.
Important Note: Measurement ranges in plastics and other materials may vary depending on the selected model and type of delay tip, ensuring both flexibility and precision in application.
