fixed infrared carbon dioxide detector transmitter

Carbon dioxide detector KB-502X is particularly applicable for the building system. There are two optional output modes which make the device convenient to be installed and operated, including analogue circuit / voltage output and one-way relay output. In heating and ventilating field, this device is widely applied for controlling the ventilating by detecting the carbon dioxide concentration. By this way, the energy can be saved at least 30%. It used imported advanced infrared sensor, which has high stability and reliability.Technical SpecificationsVoltage24V AC (50/60HZ±10%), 24V DCPower Consumption2.5 W (average)Applicable GasCarbon dioxide (CO2)SensorNDIR Non-Dispersive Infra-RedDetecting Range 0 2000ppm / 0 5000ppmAccuracy±40ppm +3% read outStability<2% (during the life time of the sensor)Nonlinearity<1%F.SPerformance Life ≤15 yearsDisplay Online concentration LCD displayResponse Time<150 sPreheat Time <5 minutesAnalog Quantity Output 4 20mA (default setting)(other optional output modes can be set through jumper wire)Control output SPST relay normally opened output(when>1000ppm,control output; when<900ppm, resume normal open)Operating Environment Temperature: 0 50°C (32 122°F)Humidity: 0 95%RH (non-condensing)Storage Temperature-40 70°C (-40 158°F)InstallationWall mountingWeight130gDimensions124mm*70mm*43mm
