  • Overview
  • Series Specifications

The CWE are non-dispersive infrared (NDIR) analyzers designed for measuring environmental CO2 concentration in ventilation systems and indoor living spaces. Their measurement range of 0-2000ppm makes them compliant with ASHRAE and other standards for ventilation control. The CWE Series provides a user-selectable 4-20mA or 0-10VDC output for versatility. Microprocessor-based digital electronics and a unique self-calibration algorithm improves long-term stability and accuracy.

APPLICATIONS

  • Controlling ventilation in response to occupancy
  • Facilitating compliance with ASHRAE 62.1-2004 standard for air quality
  • Office buildings, conference rooms, schools, retail stores, etc.

Microprocessor design increases accuracy and reduces installation time

  • Non-dispersive infrared technology repeatable to ±20 ppm ±1% of measured value
  • Innovative self-calibration algorithm...easy to maintain
  • 5-year calibration interval (recommended)
  • Low ambient sensitivity
  • Alarm relay with setpoint for direct ventilation control
  • Output 4-20mA/0-10V for flexible control system interface
  • 3-year factory warranty from date of purchase
  • Input Power 20 to 30VDC/24AC; 100mA Maximum
  • Analog Output 4-20mA, (clipped and capped)/0-10VDC (selectable)
  • Operating Temperature Range 0° to 50°C (32° to 122°F)
  • Housing Material High impact ABS plastic
  • Sensor Type Non-dispersive infrared, diffusion sampling
  • Measurement Range 0-2000 ppm
  • Accuracy ±30 ppm ±2% of measured value*
  • Repeatability ±20 ppm ±1% of measured value
  • Response Time <60 seconds for 90% step change
