ABSTRACT:
A hermetic scroll compressor includes a hermetic shell through which the pressure within the shell is monitored. In one embodiment, a housing is resistance welded into an aperture extending through the shell. An oil filled pressure sensor or a dry type pressure sensor is associated with the housing. The oil filled pressure sensor extends through an aperture in the shell. The dry type pressure sensor is located on the housing outside of the shell. In another embodiment, the shell forms the diaphragm portion of the pressure sensor.
