Guardian2: Noise and Vibration

The Guardian2: Noise and Vibration Site Boundary Monitor is designed to help you remain compliant with site noise levels, using remote monitoring and reporting of noise and vibration levels. Powered by mains battery, the Guardian2: Noise and Vibration is ideal for any construction noise monitoring, no matter how remote.

The Guardian2 includes Casella’s “mHub” logger with a built in “E-sim” simcard. The E-sim has low data costs and searches several networks to ensure the highest possible signal strength, helping to ensure good data connectivity.

Data is available in real time from our secure website http://www.casella247.com/ using a private login. A report can be readily produced for site dust or noise compliance purposes and in addition, the system provides alerts via text message or an email should limits be exceeded. Reports can be easily be automated and sent to multiple users. For example, one user can be receiving a report about pm10 monitoring dust levels, where another user can receive a report about noise risk assessment measurement levels.

The innovative Guardian2 is optionally equipped with a photoionization detector (PID) to measure for VOCs up to 6,000 ppm (parts per million), assessing the emissions and air quality of a site.

– Powered by mains (100-250VAC) battery. Solar power and battery pack options are available.
– IEC61672-1 Compliant noise measurements for accurate results measuring several parameters (e.g. LAeq, LAFmax, LN%)
– Triaxial ground vibration sensor
– Email and text alerts to nominated recipients
– Manual or automatic reports
– Add VOC monitoring capabilities to this Guardian2 using SKU 208052D/VOC

Plug In and Play

Integrated into a small, unobtrusive environmentally sealed housing, Guardian2 can be configured at the time of ordering for a variety of “agents” depending upon the specific application or requirements. Installation couldn’t be simpler; just bolt to a wall or mount on a pole, apply power and then within a few moments begin transmitting data using cellular connectivity to a secure server.
