ABSTRACT:
A pressure sensor apparatus primarily for sensing pressure in a body cavity such as the cranium, bladder or vena cava of an animal or human comprising a Bourdon or bellows type pressure gauge connected to a flexible member such as a metallic disc or corrugated bellows tambour containing a non-radioactive fluid. A discrete mass of radioactive material is connected to the pressure gauge and moves proportionally to the pressure sensed by the flexible member. A radiation detector senses the movement of the radioactive material through a window in a radiation shield.
