The 1” measuring microphone cartridge MK 102.1 is designed for acoustical measurements in research and development and also for industrial use. Some applications include audiology, the measurement of building acoustics and noise levels. The microphone cartridge is designed and very carefully constructed to ensure excellent longtime stability of the electroacoustical 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 ist protected against mechanical damage by a protection grid in which an insulated calibration grid is integrated. This allows convenient measurement of each cartridge’s frequency response curve by applying a well-defined electrostatic field (400 volts/dc, 30 volts/ac) without removing the protection grid or requiring special spacers. The MK 102.1 cartridge is side-vented. The measuring microphone cartridge MK 102.1 can be screwed onto all standard 1/2” threaded amplifiers or sound level meters using adaptor A 63.1. The measuring microphone cartridge MK 102.1 is designed for sound level meters of IEC Type 1 according to IEC 61672.
