Introduced: September 1968

Title

Titles differ between systems:

IPC: the sensing element being a flexible member yielding to pressure, e.g. diaphragm, bellows, capsule

CPC: the sensing element being a flexible membrane, yielding to pressure, e.g. diaphragm, bellows, capsule

Full Title

Full titles differ between systems:

IPC:

Control of fluid pressure > without auxiliary power > the sensing element being a flexible member yielding to pressure, e.g. diaphragm, bellows, capsule

CPC:

Control of fluid pressure > without auxiliary power > the sensing element being a flexible membrane, yielding to pressure, e.g. diaphragm, bellows, capsule

CPC subdivides this area 5x more granularly than IPC with 4 additional codes.

4 codes are CPC-only extensions.
