Title: A Dual-Range Strain Gage Weighing Transducer Employing Automatic Switching
Author: Arola, Rodger A.;

Publication Series: Research Note (RN)
Description: Describes a dual-range strain gage transducer which has proven to be an excellent weight-sensing device for weighing trees and tree-length logs; discusses basic principals of the design and operation; and shows that a single transducer having two sensitivity ranges with automatic internal switching can sense weight with good repeatability and that one calibration curve serves the entire ambient temperature range in which it is used.
Keywords: Dual-range strain gage, weigh trees
