Hardly any other working environment offers such different areas of application for a touch screen as the use in industrial plants and mines (e.g. coal mining) with a potentially explosive environment due to the use of explosive gases or dust.
Patented GFG touchscreen technology for explosion protection
Interelectronix manufactures reliable GFG ULTRA touch screens that are used in hazardous areas. They help to make workflows more efficient and ensure smooth data exchange.
The patented glass film glass touch technology is suitable for explosion protection areas Zone 1/2 (gas) and 21/22 (dust).
Applications for industry 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
Increased service life due to impact- and scratch-resistant surface
Touchscreens in potentially explosive environments must not be impaired in their function. They have to withstand shocks, blows or vibrations, as well as dust and dirt. Our ULTRA touchscreens have a robust microglass surface made of borosilicate glass. This is resistant to scratches, acids, chemicals and temperatures (tested for extreme temperatures from 70 to -25 degrees Celsius). Due to the outer micro-glass layer, the GFG ULTRA eliminates the electrical charge found in conventional polyester surfaces and which is critical in the explosion protection sector.
For very demanding environments, the GFG touchscreen is equipped with a high-quality lamination: A 3 mm chemically tempered glass is laminated to the back of the touchscreen. The total thickness of this laminated glass structure is then 7 mm. Thus, the touchscreen can absorb more than 5 joules of impact energy and still remains glove-operateable.
Easy to use even in extreme areas
The pressure-based ULTRA touchscreen can be operated universally, as it allows the button to be activated with bare fingers as well as with gloves or a pen.
High image brilliance
For readability in very bright environments, the glass film glass touch screen can also be equipped with a high-quality optical laminate. This means that the touchscreen delivers excellent contrasts and correspondingly good readability even in direct sunlight.
