Description
Siemens QPM2100 Duct CO2 Air Quality Sensor Overview
The Siemens Building Technology QPM2100 is a professional-grade duct-mount CO2 air quality sensor engineered for commercial HVAC and building automation applications. Designed to monitor carbon dioxide concentrations within air handling ducts, this sensor delivers reliable, real-time data to help optimize ventilation strategies, improve indoor air quality, and support energy-efficient demand-controlled ventilation (DCV) systems.
Key Features
- CO2 measurement range: 0–2000 PPM for accurate indoor air quality monitoring
- 0–10 Vdc analog output signal for seamless integration with BAS/BMS controllers and DDC systems
- Adjustable insertion depth probe: 2.75 to 4 inches, accommodating a variety of duct sizes and configurations
- Terminal block connection type for secure, tool-friendly field wiring
- No display model — ideal for installations where a local readout is not required
- Duct-mount form factor for direct installation into supply or return air ductwork
Application & Benefits
The QPM2100 is well-suited for use in commercial buildings, schools, offices, and healthcare facilities where maintaining proper CO2 levels is critical for occupant comfort and code compliance. By feeding accurate CO2 data to a building automation system, the sensor enables demand-controlled ventilation — reducing unnecessary outdoor air intake and lowering HVAC energy consumption without compromising air quality.
Installation Highlights
- Adjustable probe insertion depth (2.75–4″) simplifies installation across different duct wall thicknesses
- Terminal block wiring connection ensures a clean, reliable electrical interface
- Compatible with standard 0–10 Vdc BAS/DDC input channels
- Compact duct-mount housing designed for straightforward field installation
