Overview Details for CWE2D
The CWE2 Series of air quality sensors for living space are for use with BAS controllers designed to accept 4 to 20mA, 0 to 5 Vdc or 0 to 10 Vdc outputs. These sensors measure CO2 levels using a dual-beam, non-dispersive infrared (NDIR) technology. The CWE2D measures temperature as well. The CWE2 Series Economy sensor has an accuracy of ±30 ppm ±3% of measured value, features 2-wire 4 to 20mA and 3-wire voltage outputs.
- NDIR CO2 sensor
- 10K Ohm Type 2 Thermistor Temperature Sensor
- Temperature accuracy: ±1.0 °C (±1.8 °F) typical
- Lower Installation costs: 2 wire current outputs
- Competitively priced sensors
- Easy installation: large wiring terminals on baseplate screw simplify installation and service
- Flexibility: field selectable outputs
- Easy to maintain: self calibrating
