HMI Systems offer sunlight-readable displays.
Press Release Summary:
Mar 10, 2011 - Certified for hazardous gas and dust explosion zones, Open HMIs feature Intel Atom CPUs and can be fitted with 15 in. displays that utilize polarization filters to minimize glare and reflections. Displays can be adjusted up to 1,000 cd/mÂ² and are readable even in direct sunlight, with luminescence of 700-800 cd/mÂ². Capable of operating at continuously extreme temperatures from -30 to +50Â°C, HMIs are suited for oil and gas sector as well as chemical and pharmaceutical industries.

Sunlight Readable Displays for Explosion-Protected HMI Systems
Press release date: Mar 09, 2011
Many important operating and monitoring tasks are carried out at HMI systems installed outdoors. This can only be done safely and easily if the displays do not reflect ambient light too strongly. Thanks to the new solution, bulky canopies that were supposed to give shade but in practice hardly did so to a sufficient degree are no longer necessary. High Brightness displays, which caused thermal problems in explosion-protected systems in particular and which were similarly useless against glare, are also no longer necessary, as the new package does not require particularly bright LEDs. Unlike any standard filters used so far, this filter pack hardly affects the image display for viewers: although the sunlight readable displays can be adjusted to up to 1,000 cd/m², they are already easily readable even in direct sunlight with a luminescence of 700 to 800 cd/m². Certified for hazardous gas and dust explosion zones 1, 21, 2 and 22, the Open HMIs are fitted with low-energy CPUs from the Intel Atom series and consist of explosion-protected modules. These touchscreen systems can be operated in rugged environments and even at continuously extreme ambient temperatures between -30 °C and +50 °C. Numerous international certifications ensure suitability for various applications in a wide range of industries, such as the oil and gas sector, package units and the chemical and pharmaceutical industries.
