  • The LRM-274 from InfraTec is ideal for integration into flame sensor measurement instruments

    When organic substances such as wood, natural gas, petrol and various plastics are catching fire, spectral radiation of typical wavelengths is emitted. As a specialist in flame detection technology, InfraTec is expanding its range of specialized detectors that detect radiation in precisely this area. The new miniaturized multi channel detector LRM-274 is characterized by the fact that as a low-power detector it requires only one unipolar supply voltage.

    The power consumption of such components, which are also referred to as single supply detectors, is several times lower than that of conventional standard detectors. They are particularly suitable for operation in industrial fire protection and early fire detection devices. The thermal compensation of the LRM-274 ensures stable operation even in the event of severe temperature fluctuations.

    Reliability in everyday life is also the aim of a detail included in an InfraTec detector for the first time. This refers to integrated heating resistors with which users themselves test the detector if necessary and thus test the complete signal chain as well as the components. This ensures a significant degree of additional safety especially when used in flame sensors. This enables to clearly determine at any time whether the respective measurement device still functions correctly.

    Another strength of the LRM-274 lies in the preconditions offered by the detector for easy integration into appropriate equipment environments. The operational amplifiers used during signal processing work within a range from 2.7 V to 5.0 V. This allows the detector to be easily integrated into the voltage range of the subsequent processor. Apart form this, due to its thermal compensation, it requires only a very small voltage reserve. An excellent ratio between useful signals and interference signals also makes it resistant to interferences.

    Large field of view as a precondition for efficient use in practice
    In addition to its low energy consumption, the latest innovation of InfraTec is characterized by a very large field of view. Symmetrical and more than 90 ˚ wide, this allows the detection of flames at constant signal ratios even for large angles of incidence. In addition, sensitive elements with a particularly large size of (2 × 2) mm2 ensure a high signal-to-noise ratio. This results in tremendous performance, which can be measured by tangible data, such as the value of the specific detectivity D*.

    The quad channel detector belongs to the series of PYROMID® detectors. With this detector, users can measure three absorption bands simultaneously and also use a reference channel. The TO8 housing (Ø 15.2 mm) of the LRM-274 has a robust aperture window of approximately (8.5 × 8.5) mm2, which protects the detector from external influences. Its miniaturized design and optional hermetic seal support easy integration into existing systems.

  • (Mar 02, 2020)

    InfraTec presents the LRM-278, the world's first eight channel pyroelectric detector in TO8 housing.

    Pyroelectric detectors are ideally suited for gas analysis. Until now, this has been complicated if many gases should be measured. There were often simply too few measuring channels for this purpose. The new LRM-278 from InfraTec now offers exactly the right solution for this. Combining eight channels in a TO8 housing with a diameter of 15.2 millimetres this detectors is the first of its kind worldwide. As a result, the number of gases that can be measured with a single detector of this size has doubled in one fell swoop.

    Double Space Savings
    When looking at the design of the single supply detector, two details become clear, which make a significant contribution towards ensuring that such a powerful solution fits into such a small space. The first detail is the central window built directly in the cap, which all other models of the series of miniaturised multi channel detectors have, too. The correspondingly large aperture of 8.5 × 8.5 mm2 means that the LRM-278 has a very large field of view (FOV). This gives rise to its outstanding signal-to-noise ratio.

    The second detail is concealed inside the detector. There, on special chip carriers, the sensitive pyroelectric sensors, the compensation elements as well as the 2 × 2 mm2 filters are positioned directly on top of each other. Due to this stack design, there is sufficient space for all other components.

    Temperature Sensor Directly in the Detector
    The frames with sensitive elements and filters are arranged in a square each with three times three fields. With a total of eight channels, one field thus remains free – the one in the middle. At this position there is a temperature sensor. With gas sensors, the temperature is usually measured as well. Until now, this has not been possible directly in the detector, however. Measuring the temperature inside the detector, for example, provides the option of compensating the typical temperature drift of the filters very accurately by means of a calibration.

    In addition to the measurement accuracy, there are also the benefits resulting from the current mode of the LRM-278. This means that it impresses particularly by its fast displaying of signal changes and dynamic response behaviour. The resulting high signal voltage simplifies the circuit design and allows the detector to become more resilient against disturbances. The higher signal levels support the easy integration of the detector into measuring modules.

    Thanks to all these benefits, the LRM-278 is predestined for extremely complex tasks within the gas analysis. This includes the analysis of medical and technical gases, the measurement of emissions as well as applications in the field of safety technology.

  • ImageIR® 8300 hs – Measurement of fast processes combined with highest precision and futureproof flexibility

    InfraTec's camera series ImageIR® stands for infrared cameras with cooled focal-plane array photon detectors, which meet the highest demands on geometric, thermal and temporal resolution and at the same time offer excellent measurement accuracy.

    The ImageIR® 8300 hs extends this series with a new generation of high-speed infrared cameras. Combining the image format of (640 × 512) IR pixels with the exceptionally high frame rate of 1,004 Hz sets new standards. It allows thermographic images of excellent quality, even of extremely fast moving objects or highly dynamic thermal processes. Thus, exactly the moment that matters is captured with absolute precision, displayed with high resolution and precisely measured thermally.

    Due to the latest detector technology, this camera – sensitive in the mid-infrared – allows high-speed thermography in full frame format and achieves an impressively high thermal resolution of 20 mK. The radiometric image data are transferred with loss-free intelligent real-time compression - without having to use internal memory – directly via an industrial 10 GigE interface to a standard notebook for storage, control and analysis. The digital high-speed data acquisition is carried out with InfraTec's IRBIS® 3 thermography software family offering the user extensive possibilities for data analysis and documentation. The camera's wide temperature measurement range allows fast processes with large temperature gradients, such as those occurring in explosions, electrical discharges or laser machining processes, to be easily recorded. The new ImageIR® 8300 hs can be equipped with a fast rotating filter wheel to adapt the camera sensitivity to the spectral properties of the target. Equipped with up to six spectral filters, the filter wheel allows sequential measurements of high image frequency in different spectral ranges.

    Use of the latest detector technology
    The newly developed high-end thermography system from InfraTec is based on an innovative detector: T2SLS with HOT long-life technology. A complex semiconductor quantum structure forms the basis for this system, whose electro-optical properties are optimised exactly to the desired requirements. It offers an excellent signal-to-noise ratio starting at relatively high operating temperatures of about 130 K resulting in lower wear and tear on the cooling system. Thus, this thermographic camera requires significantly lower cooling capacity than conventional models, which typically operate at 77 K. This results in less stress on the integrated Stirling cooler, which in turn increases the lifetime of the camera compared to other cooled cameras. Another special feature of the ImageIR® 8300 hs is the relatively large area of the individual detector elements, which are arranged in a grid (pixel pitch) of 25 µm. The sensitivity of the detector is therefore particularly high, which means that short integration times and high frame rates can also be used for measurement objects with low temperatures.

    Flexible usage of the camera due to modular design
    As for all models of the ImageIR® series, the ImageIR® 8300 hs offers a wide range of high quality interchangeable full optics optimised for the respective focal length and spectral application. All standard full optics can be combined with an optional motorised focus unit, which can be precisely remote controlled using the camera software and allows fast motorised focusing. Thus, the ImageIR® 8300 hs fits seamlessly into the modular camera series ImageIR®. It is equipped with a lens, detector and interface module. It can be individually configured to customer requirements and tailored to the most demanding applications in science and industry. Users also benefit from additional software and hardware functions that can be added at any time and are thus prepared for changing requirements in the future. Superior and simultaneously robust design, selected materials and a manufacturing process that meets the highest quality standards ensure the best reliability, long service life and thus an excellent protection of your investment.

  • InfraTec supplies high-resolution thermographic cameras for detecting elevated body temperature

    The pandemic triggered by the coronavirus currently poses enormous challenges to public life and health care systems worldwide. A significant contribution to containing the rapid spread of the virus is the interruption of infection chains. In addition to the precautionary measures known in this field, the detection of infected people can be a contributory factor. Especially when the currently highly restrictive measures to prevent contact in daily life are lifted step by step, appropriate screening measures should be used: Highly frequented areas with a great risk potential, such as medical first-aid wards, hospitals and nursing homes, but also schools, shopping centres, large companies, sports stadiums and theatres as well as transport hubs such as airports, seaports, railway and intercity bus stations are just a few examples of where screening measures are applied. They help to minimise the spread of dangerous infectious diseases, such as the coronavirus (2019-nCo, Covid-19, SARS-CoV-2) and, in the past, the “severe acute respiratory syndrome” (SARS), the Ebola virus (EVD) and the "Middle East Respiratory Syndrome Coronavirus" (MERS-CoV), through consistent checks on individuals.

    Certainly, thermographic cameras can neither detect the virus itself nor a person carrying the virus! However, these cameras enable the precise non-reactive, contactless and planar recording of surface temperatures while using the technical temperature measurement technology known as thermography. Hence, they are highly suitable for the quick and easy detection of elevated body temperatures, which can be an indication of a possible virus infection of the people subjected to screening. Such indications must, of course, always be followed by other examination methods that allow a reliable positive or negative statement about the disease and to initiate appropriate actions! The term "detecting a fever" in the sense of a (medical) fever diagnosis is actually not permitted as a designation for the above-mentioned thermographic recording of elevated body temperatures with thermographic cameras under strict observation: One reason is that fever is a complex medical phenomenon. The other reason is that, from a purely formal point of view, the cameras used are "only" technical measuring devices and not medical diagnostic instruments.

    The thermographic temperature measurement for detection of elevated body temperature puts high demands on suitable thermographic cameras: In addition to a high thermal resolution, which can make even the smallest temperature differences visible, there must be very good stability and measuring accuracy in order to be able to reliably distinguish a person with an elevated body temperature from a person without these symptoms using critical temperature thresholds and alarm values. Another very important criterion is the required high geometric resolution, which is expressed in the number of so-called infrared (IR) pixels. This is necessary because the area that has been proven in several studies to be suitable for reliably detecting elevated body temperature at the inner eyelid angle has only a small surface area, but must be sharply mapped for error-free temperature measurement. The measurement itself takes less than a second and is usually carried out in access areas, for example at the entry control at airports, where the people who are to be screened are already lined up. Largely determined by the wide-ranging requirements of the users, the evaluation of the measured data can range from simple manual use to detect people with elevated body temperature for further examinations to automatic detection and storage.

    InfraTec thermographic cameras as instruments for detection of elevated body temperature
    The very stable and highly accurate digital VarioCAM® HD series thermographic cameras from InfraTec are based on thermally and geometrically high-resolution microbolometer FPA detectors with up to (1,024 × 768) IR pixels. They deliver brilliant 16-bit thermographic images in realtime and are therefore ideally suited as instruments for detection of elevated body temperature. Large external displays can easily be connected to the cameras via HDMI interface to visualise the high-resolution thermal images. The comprehensive range of accessories, interchangeable lenses for adaptation to local requirements, optional PC or laptop connection, the special software package THERMAL-CHECK with various functionalities as well as expert advice from experienced InfraTec engineers complete the range of services. This results in a thermography system that is optimally tailored to the requirements of detection of elevated body temperature for the individual user, and which is easy to operate and works with extreme reliability and repeat accuracy.
