CWE Series Non-dispersive Infrared (NDIR) Sensor

CWE are non-dispersive infrared (NDIR) sensors designed for measuring environmental CO2 concentration in ventilation systems and indoor living spaces. Their measurement range of 0 to 2000 ppm makes them compliant with ASHRAE and other standards for ventilation control. The CWE/CDE Series provides a user-selectable 4 to 20 mA or 0 to 10 Vdc output for versatility. Microprocessor-based digital electronics and a unique self-calibration algorithm improves long-term stability and accuracy. This series has application in Controlling ventilation in response to occupancy, Facilitating compliance with ASHRAE 62.1 standard for air quality, Office buildings, conference rooms, schools, retail stores, etc.

• Microprocessor-based design increases accuracy and reduces installation time
• 4 to 20 mA/ 0 to 10 Vdc 4 to 20 mA/0 to 10 Vdc output for flexible control system interface
