FAMILY 4193

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.

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:

Infrasound (infrasonic) measurements
Sonic boom measurements
General pressure field measurements

THIS MICROPHONE SET IS A COMBINATION OF:

The unit is assembled in a clean-room environment and sealed together, after which it is assigned one single type number and one single serial number. This means that the combined unit has better precision and long-time stability, and is handled as one complete unit.

The unit also contains TEDS, which means that information about the serial number, type and sensitivity is stored within it.

THE BENEFITS OF A TEDS MICROPHONE SET:

Better stability and precision. Because the unit is assembled in clean-room facilities, there is no contamination.
Ease of use. Your analyzer front-end and software will automatically detect the type number, serial number and sensitivity because of the built-in TEDS technology. There is no need to enter this manually for every channel.
Calibration integration. The TEDS technology means the microphone is automatically detected and identified by your data acquisition software, allowing it to be easily integrated with your calibration database.
Fewer errors. As your data acquisition software automatically knows the microphone type, serial number and sensitivity, manual inputs are greatly reduced – reducing human errors.
