MK 202 E
Common name: Microtech Gefell MK 202 E
Production Status: In production
The MK 202 E is a 1/2” measuring microphone cartridge capsule designed for acoustical measurements in research and development and also for industrial use. Applications include audiology, the measurement of building acoustics and noise levels. The microphone capsule has a fixed layer of back electret to supply the polarisation voltage. It is designed and manufactured to ensure excellent long-time stability of the electro acoustical parameters. All essential components including the diaphragm are made of nickel and the diaphragm is bonded by a special galvanic process. The rear electrode is insulated from the cartridge housing by a quartz glass plate. The diaphragm is protected against mechanical damage by a protection grid. The equalisation of the static air pressure between the inside and outside of the MK 202 E cartridge is by means of a capillary tube 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. The MK 202 E is designed for sound level meters of IEC Type 1 according to IEC 61672. Includes wooden box.
