Suitable for high-temperature exhaust testing on aircraft, the Model 377B26 Probe Microphone for aerospace engineers is comprised of four components: microphone, preamplifier, housing, and several probe tips of different lengths. The system has a maximum operating temperature of +800ºC and the probe tip diameter measures 1.3 mm. According to the company, total system cost is reduced with the pre-polarized design powered by ICP or any 2 mA to 20 mA constant current supply. This allows engineers to use existing 2-20 mA low-cost power supplies and coaxial cables which are less costly than 200V power supplies required for externally polarized microphones.
