G01D 5/24 by varying capacitance
Introduced: September 1968
Full Title
Full titles differ between systems:
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 > by varying capacitance
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) > using electric or magnetic means (G01D5/06 takes precedence) > influencing the magnitude of a current or voltage > by varying capacitance
CPC subdivides this area 3x more granularly than IPC with 2 additional codes.
2 codes are CPC-only extensions.
IPC defines codes here since 1995.
