Siemens Building Technology QPA2060 Sensor

The Siemens Building Technology QPA2060 Sensor is a high-performance solution for monitoring indoor air quality and demand-controlled ventilation (DCV). This wall-mounted unit utilizes advanced NDIR technology (Non-Dispersive Infrared) to provide stable, long-term CO2 monitoring with a measuring range of 0–2000 PPM. Engineered for seamless integration into building automation systems, the QPA2060 delivers dual 0-10Vdc output signals for carbon dioxide and room temperature, ensuring your air handling units receive precise data for energy-efficient operation.

Designed for professional installers, the sensor features a robust terminal block connection and a compact housing that mounts directly to standard recessed conduit boxes. Because the CO2 sensing element includes an integrated reference light source, it requires no maintenance or recalibration in typical commercial environments—significantly reducing truck rolls and long-term service costs for contractors. This sensor is the industrial standard for HVAC controls in high-occupancy areas like classrooms, offices, and conference rooms where maintaining optimal CO2 levels is critical for safety and productivity.

Key Benefits:

• Maintenance-Free NDIR Sensing: Eliminates the need for manual recalibration through optical infrared absorption technology.
• Active Temperature Monitoring: Provides a dedicated 0-10V signal for temperature, allowing for consolidated HVAC sensor installation.
• Flexible Operating Voltage: Compatible with 24 VAC or 15–35 VDC power supplies, fitting most legacy and modern B.A.S. architectures.
• Field-Selectable Ranges: Includes adjustable signal outputs (0-10V, 0-5V) to match specific controller requirements.
• Energy Optimization: Enables precise demand-controlled ventilation to lower operational costs by reducing unnecessary outdoor air intake.

Common Questions:

Does the QPA2060 require routine field calibration?
No, the NDIR sensing element is designed to be maintenance-free. Its internal reference mechanism compensates for aging and drift, which is a major advantage for technicians managing large facilities.

Can I use this sensor in life-safety or smoke detection applications?
The QPA2060 is designed strictly for comfort and indoor air quality monitoring within a building management system. It is not rated, tested, or intended for use as a life-safety gas detector or smoke warning device.

What is the typical mounting height for this sensor?
For accurate room air quality measurement, install the sensor approximately 1.5 meters (5 feet) above the floor. Avoid placing it in corners, alcoves, or behind curtains to ensure unrestricted airflow to the sensing elements.
