Cảm biến khí CO2 gắn phòng/ gắn ống gió DWYER MODEL: CDT

The Series CDT Carbon Dioxide and Temperature Transmitters accurately monitor
the CO2 concentration and temperature in indoor environments to help achieve energy
savings. In order to achieve a higher level of accuracy, the Series CDT includes
barometric pressure adjustment. The CO2 universal output allows users to select the
transmitter output to be 4-20 mA, 0-5 VDC, or 0-10 VDC to work with virtually any
building management controller.
For applications that require visual indication, the wall mount configurations of the
Series CDT can be ordered with an integral LCD display. To prevent tampering, the
action of the buttons can be locked out using an internal dip switch selection.
The Series CDT CO2 transmitters are available with a -S option that provides the
necessary attributes and parameters to be compliant with DSA requirements for
monitoring CO2 levels in schools. There is a front facing LED that illuminates when the
CO2 level exceeds 1100 PPM

BENEFITS/FEATURES
• Minimize inventory and save time by combining CO2 and temperature
measurements into one transmitter
• Reduces the number of devices mounted in the space with integral humidity and
temperature sensors
• Requires minimal maintenance with Automatic Baseline Correction (ABC) to account
for sensor drift
• Reduce operation costs using a low energy, reliable, and repeatable CO2 sensor • Simplify installation with backplate electrical connection
APPLICATIONS
• Demand control ventilation in schools, office buildings, hospitals, and other indoor
environments
• LEED® certification
