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

Brand: Precision Digital Corporation
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.
Features
  • 4-20 mA input loop-powered
  • Modern, sleek and practical enclosure 5-digit, 0.7" (17.8 mm) upper display
  • 7 alphanumeric character, 0.4" (10.2 mm) lower display
  • 7-Digit totalizer
  • Safetouch through-glass button programming
  • Password protection
  • 32-Point, square root, or exponential linearization
  • Rate in units per second, minute, hour, or day
  • Open collector pulse or alarm output
  • Loop or external DC-powered backlight standard
  • 3.0 V drop (6.0 V with backlight)
  • Flanges for wall or pipe mounting
  • HART protocol transparent
  • Operates from -40° to 75° C (-40° to 167° F)
