Dual Output Super-mini Signal Conditioners Pico-M Series

STRAIN GAUGE CONVERTER

Functions & Features

• Provides two DC output signals proportional to a bridge

type strain gauge utilized in load cells, pressure transducers

• Supplies required excitation voltage

• Drives strain gauges of various bridge resistance and

rated output voltage

• Excitation selectable among 2.5 V, 5 V or 10 V

• Wide-range adjustment: 0 – 60 % for zero, 40 – 100 % for

span

• Space-saving, easy-to-maintain, multi-channel installation

base
