Industrial LCD Enclosures Now Being Used on Factory Floors
Due to the constant development in display technology and the reduction in LCD and plasma television prices over the recent 24 months, now allows companies to install LCD displays on the factory floor, these are used for various applications from:
- Training staff, as a training aid
- To showcase the companies products - ideal for visitors to the plant
- To monitor production
Now the age old problem occurs when you install any computer related electronics device on a production line, were dust, fluid and staff are. If the employees are not trained in the use of the LCD television, the unit will soon fail, like wise if the TV comes in to contact with dust or fluid it will fail very soon.
This is why the need for Industrial Protective enclosures is essential, they protect the LCD from the hazardous external threats, some units protect for basic dust protection, these are IP54 LCD enclosures, now the next level also protects from dust but also fluid, these are IP65 LCD enclosures (NEMA 4X), also called waterproof LCD enclosures.
The basic principles are that the display is mounted on the internal VESA plate, cables up and the IP65 (NEMA 4X) grommets closed to give a waterproof seal around the cables, then the access door to the enclosure is locked, providing a watertight seal against the body of the case, the units should ideally be keyed different to preventing unauthorized access, as you would not want the night shift watching late night TV, would you?
Now you have to look at how you would cool the internal temperature, there are 3 standard ways, all having different uses and at different price levels. Firstly, you could use a plenum cooling system, this uses the positive air flow pressure within the enclosure, replacing hot air with cooled filtered air. Secondly, is the cooling tube option, these are similar to air conditioning units, without any moving parts, so nothing can wear out! On top of this they cost 60% less than air conditioning units and with some units, you can actually set the ideal internal temperature and it kept constant. Lastly is air conditioning, this is designed for use in Middle Eastern countries were the temperature is constantly over 100 degrees Fahrenheit.
