AO-CO2-U/A
New
Availability date:
O Sensor mede: | CO₂ (Carbon Dioxide) |
O sensor de qualidade do ar interior AO-CO2-U/A registra a concentração de CO2 no ar no ambiente na faixa de 0-10000 ppm através de um sensor infravermelho não dispersivo (NDIR). Para processamento adicional está disponível um sinal de saída linear 0-10 V / 4-20 mA ou um contato de comutação.
O balanço do ponto zero, dependendo das condições ambientais reais, pode ser realizado no dispositivo por calibração manual. O sensor de qualidade executa uma auto-calibração automática em intervalos regulares, garantindo assim uma medição de CO2 estável a longo prazo.
Measurement range CO2 | 0-2000 ppm (optional: 0-5000 ppm, 0-10000 ppm, 0-20000 ppm) |
---|---|
Accuracy | 0-2000 ppm: ±50 ppm + 2% f. mv, 0-5000 ppm: ±50 ppm + 3% f. mv, else: ±100 ppm + 5% f. mv (at 20°C, 1013 mbar, auto-calibration ON) |
Temperature dependency | CO2: 5 ppm / K |
Pressure dependency | CO2: 1,6% f. mv/kPa |
Response time (t90) | < 5 min |
Long term stability | ±1% FS/year |
Sensor | Non-dispersiver Infrarot Sensor (NDIR) |
Sensor protection | mounted inside housing |

Current consumption | Ø 100 mA |
Analogue output 0-10 V | 3-wire connection |
Alarm output | potential-free change-over contact max. 24 V (100 mA), threshold can be defined by 270° potentiometer |
Electrical connection | screw terminals max. 1,5 mm² |
Light switch program | GIRA Standard 55, pure white satin (other on request) |
Cable gland | bottom side |
Protection type | IP30 |
Protection class | III |
Working range r.H. | 0...98% r.H. in contaminant-free, non-condensing air |
Working temperature | 0...+50°C |
Storage temperature | -20...+50°C |
Initial operation | After switch-on of the device follows a self-test and the tempering, which takes ca. 10 minutes depending on the environmental conditions. At this time the analogue output drifts from the actual measurement value. |
Automatic calibration | To ensure an excellent long-term stability, in the interval of 7 days starts an automatic recalibration. This feature can be disabled on the device by DIP switch. |
Manual calibration | The manual calibration of the output signal to 400 ppm (zero point) will be started by pushing the button on the circuit board (push ca. 5 s until LED is blinking). Before this it is to ensure a non-stop operating of min. 10 minutes on fresh air. After successful calibration the LED will be deactivated. |
Installation | into in-wall junction box, diameter 55 mm |
Approvals | CE, EAC, RoHS |
