MK427 noise sensor

The MK:427 Noise Sensor is a outdoor noise measurement instrument that has been specifically designed for integration with other data logging and monitoring systems. Unlike a conventional Sound Level Meter, the MK:427 Noise Sensor converts the noise level in decibels into an industry standard 4-20mA output which can be connected to standard DCS/SCADA based systems to add a noise measurement capability. The 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 industry standard 4-20mA output allows very long cable lengths to be used without reducing the accuracy of noise levels, making the MK:427 Noise Sensor ideal for systems integration.
