Monitor environmental impact from noisy construction and demolition sites - document compliance with noise limits

Buhl & Bønsøe A/S supplies measurement instruments from Casella, which has over 200 years of experience in precision measurement equipment, and Casella now introduces the new Guardian2 monitoring system, enabling the monitoring and mapping of environmental impacts from noisy demolition and construction sites for documentation purposes such as noise limits.

With Guardian2, you can quickly map and document noise (e.g., LAeq, LAFmax, LN%), dust (PM10, PM2.5, PM1.0), and vibrations, as well as wind speed and wind direction.

Web-based user interface

Casella also introduces a new cloud-based user interface, “Casella 24/7,” which allows data to be transmitted directly to mobile devices, simplifying reporting; the system also provides notifications via SMS and email to alert one or more users if predefined threshold values are exceeded.

Quick setup and simple configuration

Guardian2 can be supplied with one or more sensors, designed for easy on-site installation; once power is connected, all sensors activate and data is automatically transmitted; Guardian2 can be powered by 100-250V power supply or a solar cell, with system design ensuring data integrity during signal loss.

Advantages of Guardian2

• Online measurement of dust (PM10, PM2.5, and PM1.0 simultaneously)
• IEC61672-1 compliant for accurate sound measurements (e.g., LAeq, LAFmax, LN%)
• Heated sampling inlet to reduce moisture/condensation
• Maintenance-free wind speed and wind direction sensors
• Triaxial vibration sensor
