Meggitt Sensing Systems, a Meggitt group division, has announced the global market introduction of the Endevco® model EM46BD, a combined 1/4" ISOTRON® pressure microphone and TEDS enabled preamplifier, designed for precision sound pressure measurements and high-level, high-frequency measurements in a variety of larger channel count aerospace, automotive and general laboratory testing applications.

The fully repairable Endevco® model EM46BD comes in a preassembled kit, consisting of both a high-precision condenser microphone and preamplifier, constructed of stainless steel for high durability. Units are assembled in a clean room environment to minimize contamination in the contacts, and are calibrated together to form a reliable acoustic measurement system. Offered with a wide audio frequency range from 10 Hz to 70 kHz and a wide dynamic range, the Endevco® model EM46BD microphone is designed according to guidelines set forth by the IEC 61094 Class 1 standard, fulfilling highest industry standards for acoustic product reliability and precision. Incorporation of TEDS technology allows for the microphone and preamplifier to be recognized by any smart-transducer compatible input module. When connected, the analyzer will derive information such as microphone type, serial number and sensitivity, which is able to be read by the application software.

Recommended accessories include the Endevco® model EM42AA handheld pistonphone calibrator, which facilitates field checks of complete acoustic measurement systems and may be used to conduct level calibrations of laboratory measurement microphones, as well as the Endevco® model 4416B ISOTRON® power supply (2-20 mA) and the model 133 three-channel signal conditioner. All Endevco® acoustic sensors and instrumentation are backed by a five-year comprehensive product warranty.
