Knestel - Model OEM NDIRflex -Non Dispersive Infrared Sensor
Our various technologies, sensors and analysis devices enable gas analysis that meets the highest demands. The measuring instruments developed by us can be found in a wide range of industrial sectors. In the automotive, environmental, medical and process technology sectors, our customer-specific solutions are successfully in use.
The project objective was the development of a NDIRflex 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.
- Analysis of up to four thermopile channels
- No moving components (filter wheels, chopper or similar)
- Temperature-, pressure- and H2O-compensation
- CAN and RS232 interface
- Measurement input for electrochemical O2-sensor
- High cost efficiency
- Emission and immission measurements of industrial and process gases
- Determination of pollutants concentrations in the air
- Maturity monitoring of fruit and vegetables
- Emission measurements
- Water analysis (TOC measurement)
