Abstract
PURPOSE: To carry out the measurement of high accuracy and high reliability and stability by providing a flexible pressure-volume change element so as to bring into contact with the sealing liquid to prevent the influence of vibration and temperature and the like to a pressure sensor.
CONSTITUTION: A pressure receiving bellows 18 of pressure-volume change element is displaced so as to make the pressure slope between the liquid contact diaphragm 7 and the throttle resisting part 12 generated by the change of pressure to be measured smaller, and the movement of the sealing liquid 8 corresponding to the change of volume due to this displacement is generated in the throttle resisting part 12 to obtain balancing again. This volume change becomes several hundreds times in comparison with only the case of semiconductor sensor 4 even when the pressure resistance of the pressure receiving bellows 18 is higher, the flow rate of the throttle resisting part 12 becomes large, and the damper effect is obtained, and the temperature expanding amount of the sealing liquid 8 to the semiconductor sensor 4 is also absorbed to the replacing device 6 by passing through the throttle resisting part 12. Thus, pulsating pressure and temperature rise and other influence of vibration or the sealing liquid are prevented and the measurement of high accuracy and high reliability can be done stably.
