January 24, 2011 - Meggitt Sensing Systems released its “Endevco Acoustic Measurement Products Selection Guide,” a single comprehensive product specification resource, detailing Meggitt’s complete range of Endevco acoustic sensors and instrumentation for automotive NVH, cabin noise, vibro-acoustic testing, appliance noise evaluation, environmental noise analysis, building acoustics, appliance noise evaluation, wind tunnel testing and other critical measurement applications. 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.
