GENERAL DESCRIPTION

CTD transducer combines a Hall Effect sensor and a signal conditioner into a

single package. This provides higher accuracy, lower wiring costs, easier

installation and saves valuable panel space. The CTD has jumper selectable

current input ranges and industry standard 4-20 mA output with a split-core case.
