Knestel - Model OEM NDIRflex - Non Dispersive Infrared Sensor - Brochure

The project objective was the development of a NDIR_flex measuring bench with modular design for different cuvette lengths. The measured values should be accessed via a CAN or rather a serial RS232 communication protocol. Furthermore, it should also be realized a heated cuvette and a Peltier cooling for the thermopile receiver. About a further measuring input, an electrochemical O₂ sensor should be evaluated additionally. A further requirement was to determine the flow of the gas to be measured and a pressure or temperature compensation of the measured values.
