Polaris Touch Panel PCs with LED technology are an enhancement of the existing Polaris Panel PCs. Available in the sizes 5.7", 10.4" and 12.1", these devices have been designed for the comfortable handling of simple machines such as mixers, dryers or filling stations and for the control and supervision of complex machines such as reactors, centrifuges or ball mills. The devices have been designed for use in zone 1 + 2 as well as in zone 21 + 22. This guarantees the habitual PC comfort also in hazardous areas. They are especially suitable for use in the chemical, petrochemical and pharmaceutical industry. The high-resolution displays with LED background illumination and touch-screen allow an intuitive and comfortable handling. Even with large viewing angles or under unfavorable light conditions, the LED display technology guarantees an optimal contrast. The well-proven LX800 processor offers sufficient processing power to display HTML pages or to serve as a remote client. This allows high-performance visualization and handling of processes on site. For a higher processing power, a high-performance Intel Atom with 1.6 GHz together with Windows 7 Embedded is optionally available. The latest visualization software for the Touch Panel PCs, BMS Graf pro Runtime 7, enables the user to work under Windows XP Embedded, e.g. to transmit projects via Ethernet, to use graphic lists or to handle an integrated user management. An intrinsically safe USB interface for USB Ex i-memory sticks is also included. In addition to that, an intrinsically safe mouse, a trackball and a touchpad can be connected. The Touch Panel PCs are available in standard versions or in customized versions. They can also be delivered in a stainless steel casing. Edited by Constanze Schmitz
