DWYER CDWP INDUSTRIAL CO2 TRANSMITTER | IP54 ALUMINUM HOUSING | NDIR SENSOR

The Dwyer Series CDWP  is a ruggedized carbon dioxide (CO₂) transmitter designed for industrial and agricultural environments, featuring a durable IP54-rated aluminum housing and high-accuracy NDIR sensing technology. 

  • No durability concerns with the rugged aluminum housing
  • No water ingress or corrosion concerns with the IP54 housing that withstands 168 hour salt spray testing
  • Reduce operation costs using a low energy, reliable, and repeatable CO2 sensor
DWYER CDWP INDUSTRIAL CO2 TRANSMITTER | IP54 ALUMINUM HOUSING | NDIR SENSOR
The Series CDWP  utilizes a single-beam, dual-wavelength non-dispersive infrared (NDIR) sensor that automatically accounts for light source aging, providing superior long-term stability and accuracy compared to standard sensors. Its robust die-cast aluminum housing is finished with a gray coat tested to withstand 168-hour salt spray exposure, protecting the internal electronics from airborne dust, debris, and splashing liquids. The transmitter offers field-selectable universal outputs (4-20 mA, 0-5 VDC, or 0-10 VDC) for seamless integration with Building Management Systems (BMS) or Programmable Logic Controllers (PLC).
PRODUCT USES:
  • Animal Husbandry: Ideal for monitoring CO₂ levels in chicken barns, swine facilities, and confined feeding operations.
  • Greenhouses: Precisely controls CO₂ enrichment for optimal plant growth in humid environments.
  • Mechanical Rooms: Monitors CO₂ levels near refrigeration systems and HVAC mechanical equipment.
  • Industrial Air Quality: Manages indoor air quality and energy savings in factories and manufacturing plants.
