Introduced: September 1968
Last revised: January 2006
Full Title
Mechanical means for transferring the output of a sensing member; Means for converting the output of a sensing member to another variable where the form or nature of the sensing member does not constrain the means for converting; Transducers not specially adapted for a specific variable > using electric or magnetic means > influencing the magnitude of a current or voltage
