From Sensor to System

Fraunhofer IPM develops and manufactures measurement and control systems according to customer-specific requirements. The system features short measurement times, high precision and reliability, even under extreme conditions.

The range of applications is large:

Exhaust gas analysis
Transport monitoring of foods
Sensors and systems for measuring smallest temperature differences.

The competencies include:

Laser spectroscopic methods for gas analysis
Energy-efficient gas sensors
Particle measurement technology
Thermal sensors and systems.

Recently, Fraunhofer IPM has also been using effects of quantum physics to harness novel sensor principles for gas and process analytics.

Photothermal Gas Analysis

Infrared laser spectroscopy is well a established technique for analyzing gases, tracing toxic, environmentally harmful or other kinds of impurities. Photothermal spectroscopy allows us to determine very small gas concentrations without the need for a long optical path or a large sample volumen.

This means: »parts per billion in microliters«.

Quantum Magnetometry for new industrial applications

Optically pumped magnetometers offer a fascinating new way of measuring extremely weak magnetic fields. Fraunhofer IPM is using this technology, which has now been commercialized, to develop innovative measurement methods for industrial process monitoring and materials testing:

»Looking into the pipe«: The magnetometers provide new possibilities for non-contact monitoring of fluents in steel pipes in accordance with the requirements of the process industry.

»Detecting cracks before they grow«: Using highly sensitive quantum magnetometers, we measure the magnetic fingerprints caused by material defects.
