June 12, 2010 – Meggitt Sensing Systems released its “Endevco Microphones and Preamplifiers” selection guide. The 16-page, full-color guide highlights precision acoustic sensors and instrumentation for vibro-acoustic testing, appliance noise evaluation, wind tunnel testing and other critical measurement applications. It offers a detailed explanation of the various available types of Endevco acoustic product technologies and their technical working principles, preceded by a series of comparative technical charts for individual acoustic sensors. Endevco prepolarized condenser measurement microphones are offered in free-field, pressure, low-cost array and random incidence types and may be used to meet IEC and ANSI standards.
Array microphones offer a lower overall per channel measurement cost and are directly compatible with ISOTRON (IEPE-type) signal conditioning, facilitating their use as drop-in replacements within existing accelerometer test system set-ups for as-needed precision noise measurements. Models may be purchased as stand-alone units or in a microphone and low-noise preamplifier combination with TEDS for larger channel count applications. Available for use with Endevco precision measurement microphones are a full range of low-noise ISOTRON preamplifiers, handheld calibrators, and accessories.
