The ProtEX-Lite PD663 is Precision Digital's most economical and compact explosion-proof, loop-powered indicator. The fact that this meter is loop-powered means that there is no need to run additional, costly power lines into a hazardous area. Like all ProtEX products, the PD663 carries FM, CSA, ATEX, and IECEx approvals for use in hazardous areas. It features a single line, four digit, display that can be easily scaled in the field for any 4-20 mA input. The PD663 is built with great looking, modern, die-cast aluminum IP68, NEMA 4X rated enclosure which includes flanges for wall or pipe mounting. This meter is available with an optional backlight feature
