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
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:

Un diafragma de acero inoxidable ajustado a presión garantiza una estabilidad a largo plazo y una robustez mecánica superiores. El tipo 4193 resistirá la prueba de caída de 1 m según la norma IEC 6006-2-32.
El tipo 4193 requiere una tensión de polarización externa y, por lo tanto, debe usarse con un preamplificador clásico. Los micrófonos polarizados externos se pueden usar a temperaturas más altas sin cambios importantes en la sensibilidad.
Este cartucho de micrófono está disponible como un conjunto de micrófonos de infrasonido con el preamplificador clásico tipo 2669 incorporado.
El micrófono TEDS se ha sellado en un entorno limpio. El TEDS está programado con la sensibilidad cargada del cartucho actual y, por lo tanto, los datos están disponibles de inmediato.
La plantilla TEDS predeterminada es para IEEE P 1451.4, pero TEDS para IEEE 1451.4 está disponible a pedido.
