In various industrial environments with high-risk and hazardous hazardous areas such as mining, metal processing, as well as chemical or painting plants, particularly robust HMI touch applications are in demand. HMI stands for Human Machine Interfaces. Such touchscreens must withstand the challenges of very specific site requirements and still function safely even in fog, dust, steam or gas.

These are areas of application in which many conventional resistive touchscreens with their polyester surface are easily scratched, even by dust. Which restricts them in their function. In addition, there must be a high vibration and shock tolerance for applications in hazardous areas and the operation of systems must be possible with the help of these touchscreens even with strong temperature fluctuations.

For example, Interelectronix offers the highest impact and scratch resistance with its patented GFG glass film glass touchscreens, which are used to control, monitor and connect processes in hazardous areas. The ULTRA touch screens, which are especially suitable for hazardous areas, are equipped with an extremely hard borosilicate glass surface. This ensures that even falling tools cannot harm the touchscreen and that production is not endangered.

Possible applications for industrial and hazardous areas Zone 1/2 (gas) and 21/22 (dust):

• Ex-Remote PC terminals
• Ex-Panel PCs for process visualization
• Ex operating devices in process automation
• Ex video and camera surveillance systems
• Ex-dosing scales
