2019-05-24 03:45:10, Microtech Gefell GmbH

In today's age of high quality and environmental awareness, accurate noise measurement is of crucial importance. MTG traditionally offers a wide range of precision measuring microphones with weather protection for temporary and permanent installations. Most microphones are approved for official calibration and can be used for legally binding measurements . Microtech Gefell's measuring microphone construction is based on more than 80 years of experience. MTG develops and produces microphones for aircraft noise monitoring systems for sound incidence measurements from above and for noise monitoring. The WME 980 is the latest product of our in-house development. The WME 980 is a weatherproof microphone system for long-term outdoor measurement, stationary and mobile noise control and the analysis of environmental and traffic noise. It consists of the MK 223 ½” measurement microphone capsule, MV 203.3 ½” measurement microphone pre-amplifier, TA 202 dehumidifier, RS 98 rain and dust shield, VW 98 windshield with bird spike and the VM 960 supply module including calibration generator. The WME 980 is equipped with a remotely switchable calibration generator, a switchable cable driver and a switchable heater resistor to prevent possible condensation under extreme climatic conditions. The calibration generator injects a sinusoidal signal into the measurement microphone capsule via an electrostatic actuator. The weatherproof microphone system can be calibrated with standard sound calibrators or the Pistonphone type 5002. The WME 980 is designed for Type 1 sound level meters according to IEC 61672.
