Noise Sensor

The MK:427 Noise Sensor is an outdoor noise measurement instrument

The MK:427 Noise Sensor is an 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. Many industrial plants have a variety of process sensors strategically placed around their site so that safety, environmental impact and efficiency can be monitored and managed, in real time, from one or more control rooms. The Cirrus Environmental Noise Sensor can be connected with unparalleled ease to such a system sending out continuous live data.
