The Outdoor microphone protection system can be used with the 495 and 485 preamplifiers fitted to the 440 and 480 sound level meters. It enables them to be used outdoors for medium to log term noise monitoring and offers protection against the effects of wind and rain. Direct rainfall is prevented from falling on the top of the microphone capsule by positioning it underneath an acoustically transparent rain shield
Related accessories
The 6737 is normally used with the C6717/X microphone extension cables that connect the remote microphone to the 6723 or 6728 waterproof kit cases. A waterproof locking connector is used on the case end of this cable and a standard LEMO connector on the end fitted to the preamplifier that locates inside the enclosure. When connection is required without using a standard CEL kit case then the C6716/X cable should be used instead.
Technical Specification
The 6737 system is designed specifically to minimize the ill effects of moisture on the measurement microphone of a 400 series logging sound level meter. High quality materials are used throughout to ensure a long working life for the accessory when the CEL meter is used outdoors for extended measurement sessions. The windscreen material is almost impervious to rain water and yet is open enough to allow the noise through to the microphone. It does not become waterlogged due to the careful design and shape that allows the natural effect of the wind to keep the material dry. Dissolved acids in the air will eventually mean that the windscreen must be replaced to prolong the effective life of the system
