CO2 sensors KSC 122 with output RS 485 (MODBUS) are intended for installation in airconditioning ducts.

The sensor can be used for any control systems compatible with the output signal RS 485 (MOBDUS). The working range is specified in the table of technical parameters. The sensors meet the ingress protection of IP 65 according to ČSN EN 60 529..

The sensor can be used for any control systems compatible with the MODBUS RTU communication protocol; communication takes place through the RS 485 bus. The working range is specified in the table of technical parameters. The sensors meet the ingress protection of IP 65 according to ČSN EN 60 529. 

The sensors consist of a plastic head, which houses a transducer to convert the CO2 concentration to a MODBUS RTU output signal. The measuring sensor is located in an external probe which is firmly connected to the electronics head. The probe cannot be disconnected from the head with electronics. The supply cable is connected to the terminal board through a grommet, which is a part of the plastic head. The base material of the head is LEXAN™ RESIN – EXL 5689. The sensor stem consists of two materials – stainless steel and Tecaform. Sensor is ensured by the unique „S head“ design invented by SENSIT s.r.o

The operating conditions to establish the correct function of CO2 modul are:

  • Ambient temperature around the sensor: -40 °C to 80 °C
  • Relative ambient humidity: 0 to 100 %
  • Atmospheric pressure: 87 to 106 kPaTESTS, DECLARATION, CALIBRATIONS
