PD6701 Vantageview NEMA 4X Loop-Powered Feet & Inches Level Meter

Data Sheet
PD6701 Instruction Manual

The Vantageview PD6701 is one of Precision Digital's most advanced and feature-packed plastic, field-mounted, loop-powered indicators designed specifically for level applications that require a feet & inches display. The PD6701 can indicate up to 399 feet, 11 and 15/16 (or 7/8) inches. The PD6701 is built in a NEMA 4X and IP65 rated plastic enclosure which can stand up to even the harshest environmental conditions. It features a dual-line display that can be easily scaled in the field for any 4-20 mA analog input. Two features that really make the PD6701 stand out are its wide viewing angle display and SafeTouch® through-window buttons. These buttons allow the PD6701 tank-side indicator to be programmed and operated through the cover window, thus eliminating the need to remove the cover in dirty or wet environments.

Why Use Loop-Powered Meters?

The most basic decision a user wishing to display a 4-20 mA signal on a digital display has to make is: should the meter be powered by line voltage or should it be powered by the 4-20 mA loop?

There are three main benefits of using loop-powered devices:

  • No additional power required
  • Easy wiring
  • Additional digital displays can easily be added in the same loop

The following diagram illustrates how a loop-powered meter is wired. Notice there are only two connections made to the meter.
