with deflection of beams of light, e.g. for direct optical indication (G01D5/40 takes precedence; )

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 (G01D3/00 takes precedence; specially adapted for apparatus giving results other than momentary value of variable G01D1/00) > characterised by optical transfer means, i.e. using infrared, visible, or ultraviolet light > with deflection of beams of light, e.g. for direct optical indication (G01D5/40 takes precedence; )
