Meggitt Sensing Systems has released the ‘Endevco Microphones and Preamplifiers’ selection guide, which features acoustic sensors and instrumentation for a range of critical measurement applications.

The 16-page, full-colour guide highlights the company’s range of recently introduced precision acoustic sensors and instrumentation for automotive NVH, cabin noise, vibro-acoustic testing, appliance noise evaluation and wind-tunnel testing.

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 pre-polarised 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 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 standalone 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 is a full range of low-noise Isotron preamplifiers, handheld calibrators and accessories.
