MK:427 NoiseSensor 4-20mA Outdoor Noise Microphone
Integrate noise measurement with a 4-20mA current loop
The MK:427 NoiseSensor is an accurate, reliable and weatherproofed self-contained outdoor environmental noise monitor that connects directly to process measurement and control systems.
Unlike a conventional Sound Level Meter, the Noise Sensor simply converts the noise level in decibels into an industry standard 4-20mA output.
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.
With the 4-20mA output, very long cable lengths can be used without reducing the accuracy of noise measurements.

- 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)
- Proven long term reliability in harsh outdoor environments
- Verification through regular scheduling for remote calibration using integrated ‘auto-calibration’ system
- Outdoor Windshield and bird spikes to protect the microphone
- Entire length of the MK:427 NoiseSensor is 1m
- Simple mounting and installation for quick deployment
Applications
The NoiseSensor is ideal for permanent/semi-permanent environmental noise monitoring applications such as Power Stations, Manufacturing sites, Petrochemical sites, Construction sites, Urban noise monitoring etc.
It is also ideal for systems integrators wishing to integrate noise motoring into their existing environmental logging products.

Live Noise Data To SCADA or DCS Systems
Unlike a conventional Sound Level Meter, the Noisesensor simply converts the noise level in decibels into an industry standard
4-20mA output, which can in turn be fed directly into a SCADA-type control system.
The live noise levels can then be displayed and stored using your own system software, eliminating the problem of installing third party software where the complexity of extra software systems or security could be an issue.
