Carbon Dioxide Sensors-CWLSXX

AIR QUALITYVERIS INDUSTRIES800.354.8556 +1 503.598.4564 www.veris.comDESCRIPTIONCDL/CWL carbon dioxide sensors maximize energy savings, while ensuring optimal ventilation. These sensors allow ventilation systems to be controlled by the amount of CO2 present in a space. The CWL/CDL Series detect fluctuations in CO2 levels and signal ventilation systems to provide an inlet of fresh air optimal for the space at a given time saving energy and ensuring tenant comfort.APPLICATIONS? Controlling ventilation in response to occupancy? Facilitating compliance with ASHRAE 62.1 standard for air quality? Office buildings, conference rooms, schools, retail stores, etc.Individual or 3-in-1 CO2, RH, and TemperatureDeluxe Duct and Wall CO2 SensorsSPECIFICATIONSInput Power 20 to 30VDC/24VAC; 100mA max.Analog Output 4-20mA (clipped & capped)/0-5VDC/0-10VDC (selectable)Operating Temperature Range CDL: 0° to 50°C (32° to 122°F) CWL: No humidity option: 0° to 50°C (32° to 122°F); With humidity option: 10° to 35°C (50° to 95°F)Operating Humidity Range 0 to 95% RH noncondensingHousing Material High impact ABS plastic CO2 Transmitter: Sensor Type Non-dispersive infrared (NDIR), diffusion sampling Output Range 0-2000/5000 ppm (programmable) Accuracy ±30 ppm ±2% of measured value* Repeatability ±20 ppm ±1% of measured value Response Time <60 seconds for 90% step changeRH Transmitter: HS Sensor Fully replaceable, digitally profiled thin-film capacitive (32-bit mathematics) U.S. Patent 5,844,138 Accuracy ±2% from 10 to 80% RH @ 25°C; NIST traceable multi-point calibration Hysteresis 1.5% typical Stability ±1% @ 20°C (68°F) annually for two years Output Range 0-100% RH Temperature Coefficient ±0.1% RH/°C above or below 25°C (typical)Temperature Transmitter: Sensor Type Solid-state, integrated circuit Accuracy ±0.5°C (±1°F) typical Resolution 0.1°C (0.2°F) Output Range 10° to 35°C (50° to 95°F)Relay Contacts: 1 Form C (SPDT) (on models without setpoint slider option) 1A@30VDC, resistive; 30W max.RTD/Thermistors in wall packages are not compensated for internal heating of product.EMC Conformance: Low voltage directive 2006/95/EC and EMC directive 2004/108/EC.EMC Special Note: Connect this product to a DC distribution network or an AC/DC power adaptor with proper surge protection (EN 61000-6-1:2007 specification requirements).Note: Rough handling and transportation may cause a temporary reduction of CO2 sensor accuracy. With time, the ABC function will tune the readings back to the correct accuracy range. The default tuning speed is limited to 30 ppm per week.FEATURES ?
