Measurement microphone cartridge MK 290 E

1/2"

Measurement capsule pair - WS2F acc IEC 61094-4 - free-field - 35 Hz to 5 kHz - 15 dB(A) to 146 dB - 200 V polarization specification The MK 290 is a selected pair of 1/2" measuring microphone cartiges for sound intensity probes. The constructive design of the cartidge is equal to that of the MK 222. The equalization of the static air pressure between the inside and outside of the cartridge is by means of a capillary tube, adjusted for infrasonic measurements, rear-vented into the preamplifier. This enables the use of the optional TA 202 dehumidifier. The cartridge uses the international standard thread 60 UNS which ensures compatibility with a wide range of calibration equipment and measurement devices available from many manufacturers.
