ABSTRACT:
A flexible diaphragm-type fluid-filled sensing device is made immune to thermal expansion and contraction errors by providing a constant volume first fluid chamber formed between the insulating block and a metal plate, a second chamber between the metal plate and a sealing diaphragm and a third chamber between the other surface of the block and a measuring diaphragm. The three chambers are connected by fluid passages and the sealing diaphragm is much more flexible than the measuring diaphragm so that any volumetric change in the fluid is followed by the sealing diaphragm without changing the volumes of the first or third chambers to which the electrical displacement sensing devices are attached.
