MEGGïTT smart engineering for extrême environments ACOUSTIC MEASUREMENT PRODUCT SELECTION GUIDE Endevco® microphones, preamplifiers and accessories highlights Prepolarized condenser measurement microphones Low cost array microphones iTEDS compliant (per IEEE 1451.1 standards) Free-field, pressure and random incidence types Microphone and preamplifier combination units applications Measurement microphones can be used to study sounds within an automobile interior, from sources such as the engine and doors. Endevco® prepolarized condenser measurement microphones, available in /s", Va", and V2" 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® (lEPE-type) signal conditioning. They can be used 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 iTEDS on-board 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, for high reliability in a variety of application environments. Available for use with Endevco precision measurement microphones are a full range of low-noise Isotron preamplifiers, handheld calibrators, and accessories. In addition, all acoustic sensors and instrumentation are covered by a five-year comprehensive product warranty.
