The PDEM series consists of dual normal beam compression wave contact transducers designed for ultrasonic thickness inspection and flaw evaluation. Built with semi-circular lead zirconate titanate (PZT) elements, these probes deliver medium dampening and medium bandwidth for clear signal clarity across various industrial materials.
Dual Element Design: Dual normal beam compression wave contact configuration for near-surface flaw resolution and thickness gaging.
PZT Crystal Technology: Equipped with semi-circular lead zirconate titanate crystals.
Bandwidth Optimization: Medium dampening tailored for balanced penetration and resolution.
Operating Range: Maximum operating temperature of 50°C / 120°F (DEM transducer series available for high-temperature applications).
Side Connectors: Features side-positioned D-type connector options across all case sizes.
