Abstract

PURPOSE: To detect easily and rapidly either one of internal or external bellows being broken from the change in pressure by determining the pressure at a spacing of bellows.
CONSTITUTION: Pressure is set higher or lower in the order of an internal peripheral side spacing 19 of bellows of a double bellows 18, a spacing 30 between an external bellows 18a, and an internal bellows 18b, and atmosphere 31 in an accommodating container. By amending the change in pressure due to the change in temperature in spacing of the bellows and obtaining the difference between the value and the actually measured pressure, judge whether either one of the internal side or the external side of the double bellows 18 is broken.
