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
  • 5-Digit, 0.7" / 17.8 mm Upper Display
  • 7 Alphanumeric Character, 0.4" / 10.2 mm Lower Display
  • Loop or External DC-Powered Backlight Standard
  • SafeTouch Through-Glass Button Programming
  • Password Protection
  • 3.0 V Drop without Backlight
  • Explosion-Proof, IP68, NEMA 4X Enclosure
  • Flanges for Wall or Pipe Mounting
  • Linear, Square Root, or Programmable Exponent
  • Operates from -40 to 75°C
  • Rate in Second, Minute, Hour, or Day
  • Open Collector Pulse or Alarm Output
