Cirrus Research plc - The MK427 Noise Sensor

The MK427 Noise Sensor from Cirrus Research is an accurate, reliable and weather proof self-contained outdoor noise monitor, specifically designed for integration with other data logging and monitoring systems.

• Self-contained noise sensor for integration with external data loggers
• Purpose designed for long term environmental noise monitoring
• Industry standard 4-20mA output
• Automatic calibration with electrostatic actuation
• Weatherproof and suitable for most outdoor applications with a range of mounting solutions and an IP65 rating

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 when using the MK:427 Noise Sensor, simply power-up the device and the measured noise level is continuously fed to the output.

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 of more control rooms.
