CDSN Carbon Dioxide Transmitter

Description: The Model CDSN Carbon Dioxide Transmitter is designed for precise monitoring of CO2 concentration and temperature in indoor environments, particularly in schools, office buildings, and other commercial spaces. Engineered to support LEED® certification and energy savings initiatives, this transmitter features digital barometric pressure adjustment for enhanced accuracy. With its universal output options, housing security feature, and minimal maintenance requirements, the CDSN transmitter offers a reliable and convenient solution for indoor air quality management.

Benefits/Features:

  • Inventory Optimization: Combines CO2 and temperature measurement in one device, along with DIP switch selectable current/voltage outputs, saving time and reducing inventory needs.
  • Integral Temperature Sensor: Includes an integral passive temperature sensor, minimizing the number of devices required for space monitoring.
  • Automatic Baseline Correction (ABC): Requires minimal maintenance with ABC functionality to account for sensor drift, ensuring accurate and reliable performance over time.
  • Energy Efficiency: Utilizes a low-energy, reliable, and repeatable CO2 sensor, helping to reduce operational costs.
  • Easy Installation: Simplifies installation with backplate electrical connections, streamlining the setup process.

Applications:

  • Demand Control Ventilation: Suitable for demand control ventilation systems in schools, ensuring optimal indoor air quality based on occupancy levels.
  • Indoor Air Quality Monitoring: Ideal for monitoring indoor air quality in office buildings, maintaining comfortable and healthy environments for occupants.
