The PD6800 is a rugged, full-featured, explosion-proof loop-powered meter ideal for demanding applications in hazardous areas or in the harshest environmental conditions.

The product is CSA Certified as Explosion-Proof / Dust Ignition-Proof / Flame-Proof and ATEX & IECEx Certified as Explosion-Proof. It is available in either an aluminum or stainless steel enclosure with 3/4" or M20 conduit connections.

It will operate down to -40°C and is approved for installation in areas where the temperature gets as cold as -55°C, however the display will cease functioning.

The meter derives all of its power from the 4-20 mA loop, thus making installation a simple matter of wiring the instrument into the existing loop.

No external power is required. Programming is performed using the four SafeTouch through-glass buttons and can be done without removing the cover. In addition, the meter can be scaled with or without a calibration signal.

The backlit LCD display consists of two lines with the addition of a 20-segment bargraph on the PD6800-0L1. The main line of the display has five full digits and is used to display the process variable.

The secondary line has seven alphanumeric characters and is used for a tag, engineering units, or displaying the input in different units (for the PD6800-0L1). For instance, on the PD6800-0L1, the top line could display the height of the tank in feet and the bottom line could display the same input in gallons.

The bargraph provides a quick visual of the current state of the process variable. The backlight makes the display visible under any lighting condition and can be powered from either the 4-20 mA loop or from a separate DC power supply.
