PD6820 Prot EX RTA Explosion Proof Loop Powered Flow Rate Totalizer 00744

The ProtEX-RTA PD6820 is an explosion-proof, loop-powered flow rate/totalizer that can display flow rate and total from an analog output (4-20 mA) flowmeter. The fact that this meter is loop-powered means that there is no need to run additional, costly power lines into a hazardous area. The display has a five digit upper display for rate, a seven alpha-numeric character lower display for total, and comes standard with a backlight. Like all ProtEX products, the PD6820 explosion-proof flow rate/totalizer carries FM, CSA, ATEX, and IECEx approvals for use in hazardous areas. Two features that really make this flow rate/totalizer stand out are a wide viewing angle display and SafeTouch® through-glass buttons. These buttons allow the PD6820 to be programmed and operated through the glass, thus eliminating the need to remove the cover in a hazardous area.
