Series CDT Carbon Dioxide/Temperature Transmitters

Description: The Series CDT Carbon Dioxide and Temperature Transmitters offer precise monitoring of CO2 concentration and temperature in indoor environments, contributing to energy conservation efforts. These transmitters integrate CO2 and temperature measurements into a single device, simplifying inventory management and installation. Featuring Automatic Baseline Correction (ABC), they require minimal maintenance to account for sensor drift, ensuring reliable performance. With options for CO2 universal output, users can select from 4-20 mA, 0-5 VDC, or 0-10 VDC outputs compatible with various building management controllers.

For enhanced functionality, wall mount configurations of the Series CDT are available with an integral LCD display for visual indication. Additionally, to prevent tampering, the transmitter includes lockout functionality for button actions.

The Series CDT CO2 transmitters are available with a -S option designed to comply with DSA requirements for monitoring CO2 levels in schools. They feature a front-facing LED that illuminates when CO2 levels exceed 1100 PPM.

Features and Benefits:

  • Combines CO2 and temperature measurements, reducing inventory and installation time.
  • Automatic Baseline Correction (ABC) minimizes maintenance for sensor drift.
  • Low energy, reliable, and repeatable CO2 sensor helps reduce operation costs.
  • Backplate electrical connection simplifies installation.

Applications:

  • Demand control ventilation in schools, office buildings, hospitals, and indoor environments.
  • LEED® certification.

Specifications:

  • Sensor: NDIR, 15-year life expectancy.
  • CO2 Range: 0 to 2000 or 0 to 5000 PPM (depending on model).
  • Temperature Range: 32 to 122°F (0 to 50°C).
  • CO2 Accuracy: ±40 PPM + 3% of reading (2000 PPM CO2); ±50 PPM + 5% of reading (5000 PPM CO2).
  • Temperature Accuracy: ±1°C @ 25°C.
  • Response Time: 2 min for 90% step change.
  • Temperature Limits: 32 to 122°F (0 to 50°C).
  • Humidity Limits: 0 to 85% (non-condensing).
  • Power Requirements: 16-35 VDC or 19-28 VAC.
  • Power Consumption: Average: 2 W; Peak: 3.75 W.
  • Output: Current: 4-20 mA (max. 500 Ω); Voltage: 0-5 VDC or 0-10 VDC (min. 500 Ω); Relay: SPST NO rated 2A @ 30 VDC; RTD or thermistor per r-t curves (depending on model).
  • Compliance: CE.
