SC 500 – CO2 SENSOR WITH CURRENT OUTPUT 4 TO 20 mA

The CO2 sensors with current output 4 to 20 mA – SC 500 is designed to measure the carbon dioxide concentration of the air in spaces protected against water.
The CO2 sensors with current output 4 to 20 mA – SC 500 consists of a plastic ribbing head where a printed circuit board with the CO2 sensor and a converter is placed to establish a communication via current output 4 to 20 mA. The CO2 value is measured by a NDIR module whose output signal is also converted to an output signal 4 to 20 mA. For the CO2 concentration sensor SC 500, there is an autocalibration function available to set the sensor at the minimum CO2 value corresponding to the outside concentration level. The CO2 sensors with current output 4 to 20 mA – SC 500 meets the ingress protection of IP 30 according to EN 60529, as amended. Suitable design and high-quality material ensure that the sensor does not feel disturbing even in the interiors with high aesthetic requirements. You can choose the color of the box white or gray.
The CO2 sensors with current output 4 to 20 mA – SC 500 is designed to be operated in a chemically non-aggressive environment; its use must be chosen with regard to temperature and chemical resistance of the head and of the individual sensors. The operating conditions to establish the correct function are:

ambient temperature in the vicinity of the sensor: 0 to 45 °C
relative ambient humidity: 0 to 95% (non-condensing humidity)
atmospheric pressure: 87 to 106 kPa
