The PB Series was designed to meet the expressed need of many customers for meters with a hard-hitting, big-dial area “industrial” look.
PB Series meters are available in many sizes, types, and ranges. Mounting stud configuration complies with ANSI standards: the number of studs is as follows: 1½” meters – 2 studs; 2½” & 3½” meters – 3 studs; 4½” meters – 4 studs. Meters in sizes 1½”, 2½”, and 3½” can be supplied in 4- stud versions at no extra cost.
AC meters in this series are offered in both d’Arsonval (rectifier type) and iron-vane versions. The latter has the virtue of greater standard accuracy and relative insensitivity to input distortion, while the rectifier type is less affected by frequency variations.
