Room air quality sensor RLQ-SD-U

indoorVOC4-20 mA

Maintenance-free AERASGARD® RLQ - SD room air quality measuring transducer with active output, automatic calibration (fixed), in an elegant plastic housing with snap-on cover, for determining the air quality in three VOC sensitivity levels (low/medium/high). The transmitter converts the measured values into a standard signal of 0-10 V or 4...20 mA (switchable). Maintenance-free AERASGARD® RLQ - W room air quality measuring transducer with active/switching output, automatic calibration (can be deactivated), in an elegant plastic housing with snap-on cover, optional with traffic light indicator (five coloured LEDs), for determining the air quality in three VOC sensitivity levels (low/ medium/high). The transmitter converts the measured values into a standard signal of 0-10 V or 4...20 mA (switchable). The 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. The air quality is detected by a VOC sensor (mixed gas sensor for volatile organic substances). This sensor determines the load of contaminated gases in the room air, such as from cigarette smoke, body perspiration, exhaled breathing air, solvent vapours, emissions from building components, etc. Low, medium or high VOC sensitivity can be selected depending on the expected air contamination.
