Cirrus MK427 Noise Sensor
Permanent and reliable outdoor microphone
The pure-analogue electronics are highly reliable and operate without any user intervention. No specialist acoustic knowledge is required – simply power-up the Noise sensor and the measured noise level is continuously fed to the output.
The outdoor microphone assembly has proven reliability for long term permanent use even in the harshest of outdoor environments where upgrade to the WS:73 extreme condition windshield is recommended.
Automatic self-calibrating system
The electrostatic calibration system provides automated remote calibration of the system using a simple +5V trigger. This allows the performance of the system to be routinely verified which ensures compliance with international standards and is both time saving and especially useful where the unit is installed in a difficult to access location.
Robust, fully weather protected Class 1 outdoor microphone
Straight forward integration with Industry standard 4-20mA current loop systems
Eliminates the need for third party software
30 to 100dB(A) standard range ideal for most applications (other options available)
