Meggitt Sensing Systems has introduced a line of Endevco acoustic sensors and instrumentation for use in automotive NVH, cabin noise, vibro-acoustic testing and appliance noise evaluation.

The instruments are also suitable for wind tunnel testing and other critical sound and noise measurement applications.

Endevco pre-polarised condenser measurement microphones, available in 1/8in, 1/4in and 1/2in diameters, are offered in free-field, pressure, low-cost-array and random-incidence types and can 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.

They can be used 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 Iteds onboard memory storage capabilities, facilitating their use within larger channel count applications.

All microphones are constructed with a stainless-steel protective grid case and housing, as well as a special stainless-steel-alloy diaphragm.

Available for use with Endevco precision measurement microphones is a full range of low-noise Isotron preamplifiers, handheld calibrators and accessories.

All acoustic sensors and instrumentation are covered by a five-year product warranty.
