The Sonatest D1B Series Transducers are engineered specifically for demanding Dual Linear Array (DLA) weld inspection applications. Featuring a fully detachable design, these phased array transducers offer superior signal clarity, reduced near-surface dead zones, and excellent versatility for field and laboratory Non-Destructive Testing (NDT). Modular connectivity ensures rapid cable replacement and low long-term operational costs.
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 Optimisation: 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.
