Advantages of Industrial Touch Screen Monitors

Touch screen technology has been with us since the early 1970s and have become increasingly popular in recent years with the advent of mobile phones and pocket pc systems. Touch screens are at once everywhere with ATMs, ticket machines and info points utilizing them. They are a key asset in industrial computing further as touch screen monitors offer certain advantages over conventional machine screens. The most obvious advantage of touch screen monitors is that they act as both an input and output device. Using a graphical user interface (GUI) there is no demand for a separate monitor, keyboard and mouse as the touch screen monitor acts as all three. In industrial applications, touch screen monitors also have the advantage of being more robust than a conventional CRT (cathode ray tube) or LCD monitor. Touch screens are often built with durability in belief and many are resistant to industrial contaminants such as water, dirt, oil and grease. Many touch screen monitors bo
ast IP65 and NEMA 4 ratings allowing the monitors to be washed-down and protected against, electrical surges, physical impact, temperature extremes, theft, tampering and airborne debris. Touch Screen monitors can also reduce the amount of a personal computer system, without separate peripherals and all those wires, they can also be mounted on walls or on the back of machines. They can also be house in industrial computer enclosures - these afford added protection from spillages, knocks, bangs and all the more explosive atmospheres. Many touch screen devices are used where guideline computer equipment is just not practical such as when a machine is positioned outside or left unattended. There are different technologies behind touch screen monitors such as resistive touch screens, capacitive systems, infrared and surface acoustic wave technology. The types of touch screen Differ in their efficiency at reading a touch and the clarity of the monitor. Some of the syste
ms are also more susceptible to scratches and contaminants. In selecting a touch screen the most salient things to remember is where the screen will be placed, what applications it will be used for, how durable does it require to be and how clear or bright does the monitor have to be.
