G01D5/34784 - 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 characterised by optical transfer means, i.e. using infra-red, visible, or ultra-violet light with attenuation or whole or partial obturation of beams of light the beams of light being detected by photocells using displacement encoding scales; Absolute encoders with analogue or digital scales with only analogue scales or both analogue and incremental scales
