Switches and sensors

rtq

The air quality room switch measures the concentration of over 30 different contaminants. The concentration is measured by the use of a special air quality sensor which is self-calibrating and maintenance free in a normal environment.

These switches monitor the air quality by a unique oxidizing element that varies in resistance with respect to the contaminant gases. The output signal corresponds to the combined concentration of more then 30 gases typically found in indoor environments and provides a much more accurate representation of the actual air quality than a CO2 sensor.

• Voltage supply: 18-32 Vdc/15-24 Vac
• Different options available
• Relay output: 1 C/O contact 250 Vac/2 A
• Air quality measurement range: 0-2000 ppm
• Sensor element: oxidizing element that varies in resistance
• High degree of stability by self-calibrating function
• Minimal cost and rapid assembly time
• Internal setpoint setting by trimmer: 400-1800 ppm
• Hysteresis: by slide switches per 25 ppm
