Rugged piezoelectric microphone for engine noise monitoring introduced by Meggitt Sensing
Sept. 30, 2012
SAN JUAN CAPISTRANO, Calif., 30 Sept. 2012. Meggitt Sensing Systems in San Juan Capistrano, Calif., is introducing the Endevco model 2510 sound pressure level piezoelectricmicrophone for extreme acoustic measurement applications such as rocket launch separation studies and high-temperature aircraft engine noise monitoring.
The rugged sound sensor is designed to measure very high-intensity acoustic noise and very low pressure fluctuations over a wide temperature range.
The device has a sound pressure measurement range of 100 to more than 180 dB SPL and temperature measurement capabilities from -55 to 260 degrees Celsius.
The sensor has a hermetically sealed stainless steel housing enclosing a thick pressure diaphragm that resists puncturing, particle impact damage, accidental mishandling, or high pressure pulses.

Handheld test and measurement instrument that produces transducer outputs introduced by Meggitt Sensing.
Insulation placed between the transducer and mounting surface prevents electromagnetic interference (EMI or ground looping) that can degrade data quality and lead to measurement uncertainty.
Units feature integral vibration compensation within the sensing element and insensitivity to altitude changes to make them suitable for airborne applications.
