Veris CWE2 Economy Wall Air Quality Sensor

FEATURES 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 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 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 Datasheet SPECIFICATIONS CO2 Measurement Accuracy : ±30 ppm ±3% of measured value CO2 Measurement Range : 0 to 2000ppm CO2 Measurement Repeatability : ±20 ppm ±1% of measured value CO2 Measurement Resolution : 1 ppm CO2 Response Time : =75 seconds for 90 degree step change CO2 Sensor Type : Dual beam on-dispersive infrared (NDIR), diffusion sampling Color : Matte White Electrical Wiring Size : Screw terminals, 18-24 AWG Enclosure Material : High impact ABS plastic Humidity Measurement Accuracy : ±2% from 10 to 80% RH @ 25°C (77 °F) IP Protection : IP20 Input Specifications : Class 2; 20 to 30 Vdc, 24 Vac, 50 to 60 Hz Measurement Type : CO2 Operating Current : 20mA Operating Humidity : 0 to 95% RH non-condensing Operating Temperature : 0 to 50 °C (32 to 122 °F) Output Specifications : Selectable 4 to 20 mA (2-wire), 0 to 5 V (3-wire), 0 to 10 V (3-wire) Outputs : Analog Standards EMC : EN61000 Series – industrial immunity Standards : CE, UL 916, RCM, ICES-003.
