WME 980 AM Weatherproof Microphone Unit sound incidence vertical to the microphone axis • 20 Hz to 20 kHz • 15 dBA to 149 dB • LEMO® ERD.2S.306 • Power supply: 6 V DC to 25 V DC • remote calibration with electrostatic actuator The WME 980 AM is a weatherproof microphone unit for permanent outdoor measurement as well as stationary or mobile airport noise monitoring. The housing is made of stainless steel and is equipped with a bird spike, windscreen and rain shield. Inside the housing are easily exchangeable dehumidifier bags with silica gel and an easily exchangeable dehumidifier adapter TA 202 L with a humidity indicator window is part of the measurement microphone. The weatherproof microphone unit has a pole adapter with a G 1.5“ thread for installation. A tripod adapter or G 1“ thread adapter can be screwed directly to the pole adapter. Delivery Weatherproof Microphone Unit with adapter G 1.5“ to 3/8“and hook wrench 45-50 mm in aluminium case 450 mm x 365 mm x 160 mm The output connector is located well-protected at the lower end of the housing under the pole adapter. The weatherproof microphone unit can be calibrated with standard 1/2“ sound calibrators. For remote calibration, a remotely switchable, builtin calibration generator feeds a 1 kHz calibration signal into the measurement microphone via an electrostatic actuator. Inside the housing there are switches for the cable driver and the microphone heater, which prevents condensation under extreme climatic conditions. The weatherproof microphone unit is suitable for sound level meters of Type 1 acc. IEC 6167
