PD6801 Explosion-Proof Loop-Powered Feet & Inches Level Indicator

Brand: Precision Digital Corporation

The PD6801 is a rugged, full-featured, explosion-proof loop-powered meter specifically designed for level applications in hazardous areas or in the harshest environmental conditions.

Instead of the usual decimal display, the meter displays level in feet, inches, and fractions of an inch with a 20-segment tank level indicator.

The secondary display can show a custom unit or tag, percent full, or a second scale for the 4-20 mA input used to indicate volume.

The backlight feature 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.

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" NPT or M20 conduit openings. 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.
