Duct humidity, temperature, air quality and CO2 sensor AERASGARD® KFTM-LQ-CO2-Modbus

Patented quality product (patent no. DE 10 2014 010 719.1)

Maintenance-free AERASGARD® KTM - CO2 - SD/ KFTM - CO2 - W duct air quality measuring transducer with active output, automatic calibration (fixed), in an impact resistant plastic housing with quick-locking screws, for determining the CO2 content of the air (0...2000 ppm/0...5000 ppm) and the temperature (–35...+80 °C). The transmitter converts the measured values into a standard signal of 0-10 V.

Maintenance-free AERASGARD® KFTM - LQ - CO2 - W duct air quality measuring transducer with active/switching output, automatic calibration (can be deactivated), in an impact resistant plastic housing with quick-locking screws, optionally with/without sisplay, for determining the CO2 content of the air (0...2000 ppm/0...5000 ppm), the quality in three VOC sensitivity levels (low/medium/high), the temperature (–35...+80 °C) as well as the relative air humidity (0…100% r.H.). The transmitter converts the measured values into a standard signal of 0-10 V or 4...20 mA (switchable).

These sensor devices are 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.

A long-term stable, digital humidity and temperature sensor guarantees precise measuring results.

The CO2 content is measured using an optical NDIR sensor (non-dispersive infra-red technology). The detection range is calibrated for standard applications such as the monitoring of residential and conference rooms.
