influencing the magnitude of a current or voltage

Introduced: September 1968

Full Title

Full titles differ between systems:

IPC:

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

CPC:

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

Of 6 combined children, 5 exist in both systems.

1 codes are CPC-only extensions.

1 shared codes have differing titles between IPC and CPC.
