36 GAS DETECTION
Gas detection series simplifi es refrigerant safety compliance Bacharach announces the introduction of the MGS-400 Gas Detection Series for commercial and industrial refrigerant and gas leak detection applications.
The MGS-400 gas detectors support safety compliance inside of machinery rooms, mechanical equipment rooms, chiller plants, cold storage facilities and walk-in freezers by monitoring for dangerous refrigerant leaks for numerous gases including HFCs, HFOs, HCFCs, CO2
leaks and quickly initiate alarm systems helps to protect personnel and achieve compliance with safety standards like ASHRAE 15, CSA-B52 and EN 378.
MGS-400 Gas Detectors are supported by a mobile app user interface, making confi guration, calibration, and maintenance simple and intuitive. Reducing commissioning and installation time, the MGS-400 delivers on effi ciency and cost savings while allowing for plug-and-play, pre-calibrated sensor installation and replacement in the fi eld. Using the mobile app and plug and play sensors, gas detectors are installed in signifi cantly less time, for example, 5 minutes vs 25 minutes per detector without training. Calibration certifi cates can be generated from the mobile app and sent by email or shared to cloud storage platforms.
The optional MGS-408 Gas Detection Controller supports up to eight sensor channels and enables a centralized alarm and power system. With Modbus connectivity, the controller integrates with any facility’s existing building management or automation system. The MGS-408 also connects with Bacharach’s MGS-250 IR-based refrigerant monitor and the dual-sensor MGS-550, allowing for fl exibility of individual site requirements. Power and communication connectivity from the controller to all sensors can be done with a single cable in a daisy-chain design.

New, high-end, mid-infrared range camera offers superb
performance in industrial and lab settings Infratec’s new ImageIR® 9500 performs effectively in a wide variety of applications where tests in the mid infrared range are needed. These cameras can perform site surveillance including monitoring of fi re hazards in industrial settings such as waste and recycling plants and factories, fi nd the smallest temperature differences in landscapes, biotopes and labs, search electrical installations or high-voltage nets for dangerous hotspots among their almost endless range of capabilities.

The ImageIR® 9500 features a cooled FPA photon detector. This is based on highly sensitive mercury cadmium telluride (MCT) and has a 16:9 HD format with (1,280 x 720) IR pixels. Due to its high native geometrical resolution, even the smallest structures on the largest of objects can be analysed in detail. The combination with a high-performance microscopic lens enables the display of structures of up to 1.5 µm in size. Users save valuable time by reducing the number of required single recordings, while avoiding geometrical measurement errors.
InfraTec´s unique MicroScan function further enhances the camera’s effi ciency because geometrical resolution can be increased to 3.7 Megapixels in full-frame. Images of this quality show the measurement objects in extremely high resolution.
With such high levels of precision, the ImageIR® 9500 is ideally suited for use in scientifi c and research institutions, anywhere in the world. This camera offers thermal resolution of up to 0.025 K., and enables reliable detection of very small temperature differences on measurement objects and creates the criteria for creating noise-free thermal images. IR frame rates of up to 1.5 kHz in quarter-frame, together with extremely short integration times of only a few microseconds, enable users to analyse fast-running thermal processes.
Comparable to other infrared cameras of Infratec’s ImageIR® series, this model is also extremely fl exible to confi gure. The camera comes with latest detector linear cooler technology. Its modular design provides convenient retrofi tting with components such as motorised focus, internal high-speed shutters as well as motorised fi lter respective aperture wheels. This means that users can easily solve their measurement tasks – no matter what fi eld of application they are working in.

Gas sensors offer protection for research
on hydrogen cars Anyone who talks about electric cars usually envisages the ones with batteries to store electricity. It has long been known that there are also other ways. Fuel cell electric vehicles use hydrogen as a storage medium; the cell generates electricity and the electric motor provides the drive. Only water vapour is produced, but no exhaust gases at all. In the production of hydrogen, however, monitoring by a gas warning system is indispensable. During research work, leaks can occur at any time and cause catastrophic damage in the event of ignition. MSR-Electronic’s PolyXeta®2 with its innovative exchangeable sensor, X-Change, is widely used for successful gas monitoring with defi ned SIL requirements. The research on hydrogen cars is regarded as an enlightened vision of the future. Not least because hydrogen is clean, safe and almost infi nitely available. In fact, this element is so common that it accounts for more than 2/3 of all materials in the world. This means that H2 can always be produced locally due to its ubiquitous nature.
A well-known automobile manufacturer in Baden- Württemberg attaches importance to high safety in its development department for hydrogen-powered vehicles, thus needing a reliable monitoring of gas concentration in order to detect the volatile organic hydrogen molecules. Highly robust PolyXeta®2 sensors from MSR-Electronic can display a precise and stable hydrogen content in the air after remote calibration. The measuring method with integrated temperature and drift compensation stands for highest accuracy and reliability with the long service life of the sensor. The device has a standard 4-20 mA analogue output and two relays with adjustable switching thresholds. In the emergency of a leakage, an early warning of the occurrence of an ignitable gas concentration and countermeasures can be initiated. The step-by-step conversion of 190 transmitters and the maintenance is carried out by the partner Gawado Gaswarnsysteme in this project. Of course, hydrogen has to be produced in the fi rst place, because it does not occur in this form in nature. Unlike oil, hydrogen is not a limited raw material. The largest manufacturer is the chemical industry producing hydrogen as a by-product or co-product – this alone would be enough to operate 750,000 vehicles in Germany according to the technology group Linde. Hydrogen forms bi-molecules H2 and is present in gaseous state at room temperature. In its pure form, hydrogen is an invisible, odourless and non-toxic gas. There are various methods of producing hydrogen, such as steam reforming or electrolysis. In addition, hydrogen is also relatively easy to store and transport. It is thus one of the most important energy carriers of the future. Hydrogen is very highly fl ammable. The gas reacts violently with air, oxygen, halogens and strong oxidizing agents.
