The MK 201 is a 1/2” measuring microphone cartridge 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 cartridge 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 201 cartridge is by means of a capillary tube side-vented into the atmosphere. 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 microphone cartridge MK 201 is designed for sound level meters of IEC Type 1 according to IEC 61672.
