1/2" LOW FREQUENCY PRESSURE FIELD MICROPHONE
Low frequency microphone Type 4193 is designed for infrasound measurements over a frequency range of 0.07 Hz to 20 kHz. The microphone is externally polarized and must be used with a classical preamplifier.
FAMILY 4193
Type 4193 Low Frequency Microphone is built for making infrasound measurement in ship engine rooms, in helicopters and in wind-buffeted buildings, due to its extremely low cut-off frequency.
When used with Infrasound Adaptor UC-0211, the lower limiting frequency of the preamplifier is reduced to 0.1 Hz.
Pressure-field microphones are optimised to have a flat frequency response in a pressure field, and work well for making measurements in small, closed couplers or close to hard, reflective surfaces. The microphone is an ideal choice when making:
