Loop-Powered Meters Model PD660, PD661 Precision Digital

Use this 4-1/2 digit Loop-Powered Meter 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!

The new Loop-Powered Meter is 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.

The PD677-N-EX, PD677-A-EX, PD678-N-EX and PD678-A -EX have been FM, CSA and CENELEC approved as explosion-proof as complete products- not just the enclosures.
