G01D5/2452 - CPC Classification

Classification description:

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 characteristics of pulses or pulse trains; generating pulses or pulse trains using a variable number of pulses in a train; Incremental encoders incorporating two or more tracks having an (n, n+1, ...) relationship
