Model PD673, PD674, PD675, PD676, PD677, & PD678 4-1/2 Digit Loop-powered Meters
Use these 4-1/2 digit Loop-powered meters to display numbers up to 19,999 with 1 count resolution. That is, they will display numbers like 7124, 15697 or 124.78 as "whole numbers" -- no dummy zeroes or multipliers needed! These new meters are also available in 3 enclosure types: Panel mount, NEMA 4X, and Explosion-proof so they can be located almost anywhere in the plant. Options include open collector high-level-alarm output and square root extraction.
