oem NDIRflex non dispersive infrared sensor

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.

Chemiluminescence detector (CLD) for
NOX measurement

Chemiluminescence detector (CLD) for
NOX measurement

The project objective was to develop a device for measuring the concentration of nitrogen oxides (NO and NOX ) in the exhaust gas of vehicles and combustion processes. The challenge here was to achieve an enormously high dynamic range with measuring ranges between 0-100 ppm and 0-3000 ppm. The detection limit was to be only a few parts-per-billion. Another challenge was to minimize the falsification of the measurement signal by interfering components, such as water and carbon dioxide. In addition, the device had to be designed for a limited installation space.

LAS-OEM Quantum cascade laser spectroscopy for N2O trace gas analysis

LAS-OEM Quantum cascade laser spectroscopy for N2O trace gas analysis

The project objective was the development of a compact, well-integrable analyzer module consisting of a long way cell (Herriott) and an laser control electronics for trace gas analysis of N2O. Beside N2O, the gases CO, CO2 and O3 shall be determinable. A fast response time (t90: 1-2 seconds), no cross-sensitivities to other gases, and a low detection limit
of < 10 ppbV are the characteristic conditions that were set on this project.

PAS-OEM sensor module for gas analysis

PAS-OEM sensor module for gas analysis

The project objective was the development of a photoacoustic sensor for the measurement of
NO2 -concentrations in exhaust gases with a detection limit of < 50 ppb using the photoacoustic principle.
A particular challenge was to perform the measurement independently of ambient or flow noise.
Another project goal was to operate the cell in acoustic resonance, for which procedures for stabilization had to be developed (resonance tracking). This allows continuous measurement under gas flow, independent of changes in
temperature or gas concentration.
