This 292mm-long, 418g aluminum alloy noise transducer for vehicles runs on DC 9 - 30V. It measures 30 - 130dB(A), with - 38±3dB sensitivity, 0.1dB resolution, and ±3dB accuracy. Operating from 20Hz - 12.5kHz with 200ms response, it has a 0.5 - inch omnidirectional electret mic. Max power is 500mW, with IP55 protection. Package includes 1 transducer, 1 cable, 1 manual. High accuracy for vehicle noise, wide voltage use, build, IP55 protection Connect red to positive, black to negative, yellow for signal with power off. Install in vehicle, power on after checking, and measure by the manual. For vehicle makers, mechanics, and those testing vehicle noise. Used in vehicle production, maintenance, and in - vehicle noise monitoring. Key params: 292 mm, 418 g, DC 9 - 30 V, 30 - 130 dB(A), - 38±3 dB, 0.1 dB, ±3 dB, 20 Hz - 12.5 kHz, 200 ms, IP55. Precautions: check package, no power - on connection, mind wire length, don't damage sensor › See more product details; Product description Item type: noise transducer.
