Jim I created an illustration based on your concept as in outer oil housing
and internal air housing for eletric motor.
I have shown the location for a pressure sensor within
the closed stem at the top of the outer housing and at the bottom a stem
for the drain/fill/pressure up component not shown.
Is this sort of what you mean with regards to seals and using oil to
indicate you water passing the seal and increasing the differential pressure
between the two housings? Lawrie
