½-INCH PRESSURE-FIELD MICROPHONE, PREPOLARIZED, 5 HZ – 20 KHZ
Pressure-field microphone for precision coupler measurements, random incidence, and free-field measurements with 90° incidence over a frequency range of 5 Hz to 20 kHz.
TYPE 4971
Type 4971 is a high temperature, CCLD pressure-field microphone set optimized for measurements in 125°C. The microphone is ideal for coupler measurements, random incidence measurements and free-field measurements with 90° incidence.
Being prepolarized, it can be used with CCLD input as well as classical input. It has wide frequency and dynamic range and is highly immune to changing environmental conditions.
