Abstract

PURPOSE: To achieve the prevention of overpressure and the prevention of temperature and static pressure errors by providing the pressure transmitting media contained respectively in the split main body cases and sealed by the diaphragm displacing with the pressure to be detected.
CONSTITUTION: When the pressure Pa exceeding the elastic limit of a pressure sensitive element 37 is supplied, a bellows 65 is moved by way of a diaphragm 40a and a pressure transmitting medium 43a according to this and as it stops the pressure medium 43 is sealed respectively between the bellows 65 and auxiliary elastic body 38. Further as an excessive pressure is applied, an O-ring 56a deflects and this causes the pressure transmitting medium 43a of the O-ring 56a portion to move to the bellows 65 and pressure sensitive element 37 sides but the volume Va portion thereof will not be supplied as a pressure change to the pressure sensitive element 37. Hence, the output of the time when the O-ring 56a abutted against the protruding part 57a is maintained.
