Precision Digital ProtEX-RTA Rate/Totalizer, Digital PD6820

PD6820 ProtEX-RTA Explosion-Proof Loop-Powered Flow Rate/Totalizer

Brand: Precision Digital Corporation
Add Product to My Catalog

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 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.
