the uni-pot signal conditioners have been designed to enable the user to adapt the output impendence of linear or rotative displacement transducers potentiometric with acquisition systems or plc, in a way that does not alter the linearity of the transducer itself. features:- 1.high impendence input >80mohm 2.voltage output 0~10vdc 3.current output 4~20ma 4. linearity error
