Details
Duct CO2 Transmitter, 0-2000 ppm, 100 ohm Plat RTD Temp Sensor
Outputs 4-20mA, 0-5V, or 0-10V, selected in the field, and needs 24 VAC/DC power.
Self-calibrates, so the space must return to about 400 ppm for at least an hour a day; for 24-hour occupancy Greystone recommends the CD2 series.
Provides the temp sensor as a separate passive 2-wire resistance output.
Key Features
- Accuracy: +/-(30 ppm + 3% of reading)
