PCB Piezotronics’ surface microphone for R&D testing features a low-profile design ideal for testing in confined spaces and windy environments. The low-profile (1/8-in height) microphone and surface mount pad reduces the impact of undesired air pressure on the microphone during the measurement process. Model 130B40 is an all-in-one, prepolarized microphone and preamplifier combination with a water- and dust-resistant cover. Maximum dynamic range allows measurements to 142 dB and a 32 dBA low noise floor. TEDS v1.0 is standard. Applications include sound pressure measurements in space-constrained cavities, environmental testing or Clear Air Turbulence (CAT), tornado research, wind tunnel testing, or general sound analysis where wind noise may be an issue.

Industrial aluminum slabs are typically produced by blending small amounts of copper or manganese in a reservoir of molten aluminum that is rapidly cooled, a process known as direct-chill casting. Variations in the way these elements solidify can yield uneven results that weaken the final product.
