Acoustic sensors, instrumentation

September 3, 2010

Meggitt Sensing Systems, a Meggitt group division, has released a selection guide for its Endevco® microphones and preamplifiers.

The 16-page guide highlights the company’s new precision acoustic sensors and instrumentation for automotive NVH, cabin noise, vibro-acoustic testing, appliance noise evaluation, wind tunnel testing, and other critical measurement applications. It offers detailed explanations of the products and their technical working principles, preceded by a series of comparative technical charts for individual acoustic sensors.

The prepolarized condenser measurement microphones are offered in free-field, pressure, array, and random-incidence types and may be used to meet IEC and ANSI standards. The array microphones are directly compatible with ISOTRON® (IEPE-type) signal conditioning, facilitating their use as drop-in replacements within existing accelerometer test system setups 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 large channel count applications.
