Common applications using InfraTec Pyroelectric infrared detectors include:

  • NDIR gas analysis
  • IR flame detection
  • A variety of analytical instruments for detection of radiation from deep UV to FIR (THz)
  • Single and Multi-channel pyrometers

There are also a growing number of diverse applications (some surprising) that use InfraTec thermal detectors. Please let us know if your application might benefit from our highly stable, high performance, and highest quality pyroelectric infrared detectors.

Tunable Filter - New MEMS Microspectrometer for Infrared Absorption Spectroscopy

GAS DETECTORS / GAS LEAK DETECTION – By mounting a NBP (Narrow Band Pass) filter in front of our infrared detectors, our device will produce a signal when a pulsed or “chopped” source is used to illuminate it. The absorption region of CO2 gas is 4.26µm so placing a NBP filter at this spectral region in front of our device allows it to see only that region. When CO2 gas leaks into the detector’s Field of View the user would see a drop in the device signal when the gas absorbs light energy. In some cases a second “Reference” detector with a 3.95µm filter is used so that the comparison between the two channels gives further evidence of a leak.

FLAME DETECTION – Hydrocarbon flames emit radiation between 4-4.6µm and the natural 10 Hertz flickering of any flame is a natural source for our detectors mounted with an “HC” filter. Many clients use this solution to protect lives at chemical and petroleum plants as well as general building safety.

ALCOHOL TESTING – Another application in the gas detection market is the testing for an illegal level of alcohol in the breath of a driver. Very accurate readings can be obtained as legal evidence for DWI cases. This concept is being taken a step further with the discovery that certain illnesses cause gases to form in the lungs that are not normal, specifically in the case of cancer. By being able to detect certain gases, a quick and inexpensive method of diagnosis may be possible.

ANESTHESIOLOGY TESTING – Another gas detection application is the use of our detectors to test for the correct level and mixture of gases used in hospital operating rooms for anesthesiology. Too much, or too little of one component could be fatal.

PETROLEUM EXPLORATION – A number of companies are using our detectors for high-temperature down-hole operations as well as topside. Production testing for gas levels below and on the surface is important to determine if drilling operations are proceeding as planned.

PLANT HEALTH – Imagine having a device that can test the level of CO2 absorption to analyze the health of plants and check the effect of global warming…it is being done today.

RAIL SAFETY – Testing is underway for a device that will “look” at rail cars to test brake and wheel bearing temperatures on the move. This is critical, especially for high speed rail in Europe to detect potential failures before they happen.

SPACE OPERATIONS – InfraTec is qualified by the European Space Agency for use on platforms for Earth limb detection for satellite orientation and will potentially see applications in LIDAR applications in the future.

TEMPERATURE SENSOR – Our sensors can recognize temperature changes on rotating devices like motors and power generators so that the potential failure of a post can be detected long before a total failure occurs. This allows for spot repairs of small items before it causes more extensive failures.

UNDERGROUND SOLUTION – The detection of Methane and other gases in mining operations is very critical to the safety of operations around the world. Many customers use our highly reliable devices to protect the lives of those that work long hours beneath our feet.

WATER and STEEL ANALYSIS – Clients use our devices to test gases emitted from water as it is boiled down to test for and identify impurities. In the production of steel, the same process can be used to test for correct mixture of elements by super-heating steel pellet samples and observing the level of known gases for quality and content. This gives controllers an opportunity to make corrections before molding or processing the molten metal.
