About this technology
Overview
Trig-Tek, Inc.'s Model 251A ACL-8 Anderson Current Loop Conditioner is an eight channel device designed to condition variable-resistant senor signals from Strain Gage and RTD's. It uses NASA's patented ACL technology instead of the classic wheatstone bridge. The electronic measurement circuit delivers accuracy far beyond previous methods and prevents errors caused by variation in the wires that connect sensors to data collection equipment. This is the first license to market a NASA Dryden Flight Research Center patent.
