S+S Regeltechnik KCO2-SD Duct CO2 Sensors And Measuring Transducers

Maintenance-free duct sensor AERASGARD KCO2-SD with active output, automatic calibration (fixed), in a compact plastic housing with quick-locking screws, for determining the CO2 content of the air (0…2000 ppm/0...5000 ppm). The measuring transducer converts the measured values into a standard signal of 0 -10 V. Maintenance-free duct sensor AERASGARD KCO2-W with active/switching output, automatic calibration (can be deactivated), in a compact plastic housing with quick-locking screws, optionally with/without display, for determining the CO2 content of the air (0…2000 ppm/0...5000 ppm). The measuring transducer converts the measured values into a standard signal of 0 -10 V or 4...20 mA (switchable). The CO2 sensor is used in offices, hotels, convention centres, apartments, shops, etc. for the purpose of evaluating the indoor climate. This enables energy-saving room ventilation on an as-needed basis, thereby reducing operating costs and improving well-being. One sensor for every 30 m² of room area is recommended. The CO2 measurement is performed using an optical NDIR sensor (non-dispersive infra-red technology). The detection range is calibrated for standard applications such as monitoring residential rooms and conference rooms.

Technical Data:

Power Supply:

Voltage: 24 V AC ⁄ DC (± 10 %)
Power Consumption: < 1.5 W ⁄ 24 V DC typical; < 2.9 VA ⁄ 24 V AC typical; Peak current: 200 mA

Sensor:

Type: Optical NDIR sensor (non-dispersive infra-red technology)
Calibration: Manual calibration via zero button for KCO2 - SD; Automatic calibration (fixed) for KCO2 - SD; Automatic calibration (deactivatable via DIP switches) for KCO2 - W

Measuring Range:

Multi-range switching (selectable via DIP switches):
