Product Description:
space
 
The E Series edgewise family of panel meter products were designed to handle applications where panel space is at a premium. These meters can be mounted horizontally or vertically and meet ANSI C39.1. Accurate to within ±2% of full scale in DC and ±3% for AC, they are behind the panel mounted and come in a variety of sizes and ratings.

Scaling: Customized to any scaling desired, from linear to specialized Cos Ø, square root distributions, with color applications for visual emphasis and to any desired engineering units.
Specific accuracies
Basic Accuracy: ±2.0% of full scale basic accuracy class.
Rectifier Type Meters: ±3% of full scale basic accuracy class.
Repeatability: ±2% for Pivot and Jewell

±0.5% for taut Band

Position of use: Vertical (scale) standard

or to specified angle or position

Full scale deflection: 90 °
Movement: Taut Band
The absence of friction
resulting from this permits greater sensitivities
and provides more rugged meters.Common
failures of conventional meters subjected to
shock testing are cracked jewels and/or
blunted pivots.
Pivot and Jewel
In this design the coil and pointer are
supported by polished steel pivots at each
end which fit into jewel bearings. Pivot and
jewel meters are recommended for high vibration
environments because of the
mechanism’s inherent stability and strength.
Accuracy and repeatability are almost equal
to the taut-band’s, and good performance
from the pivot and jewel construction is the
reason for its long popularity.
Case: .5E has a thermoplastic front and steel back; all models have thermoplastic window, except models 320-ED and 320-EG, which have sealed glass; model 320-EG is constructed to withstand rough environmental and industrial applications
