Your process plants may well include areas requiring aggressive washdown, leaving you with the problem of protecting operator interface panels. These areas may also require you to provide extensive graphical operator interface to your plant personnel, and possibly local control, necessitating use of a rugged industrial PC with an integral display.
There are many IP65 products on the market, which are “Able to protect against water jets. Water projected by a nozzle (6.3 mm) against enclosure from any direction shall have no harmful effects.” But aggressive washdown often exceeds these parameters, calling for higher degree of protection
In many cases, IP66 protection is required, as it is “Able to protect against powerful water jets. Water projected in powerful jets (12.5 mm nozzle) against the enclosure from any direction shall have no harmful effects.”
When IP66 protection is required, along with a truly flat screen and bezel with no place for dust or water to collect, Advantech’s 12" and 15" Touch Panel Computers (TPC-1251T and TPC-1551T) will meet your needs.
