Title: Pressure sensor
Inventor: KODAMA SEIKI
IPC: G01L19/04
Filed: 1990-09-26
Abstract: PURPOSE:To make the pressure detection hard to be influenced by the ambient temperature change thereby to prevent the erroneous detection by absorbing the volumetric increasing amount of a pressure transfer liquid resulting from the temperature rise by a heat shrinking body. CONSTITUTION:This sensor has a diaphragm 5 installed in a casing 1, a detecting part 2 provided in the casing 1 for detecting the pressure, and a bush 10 made of heat shrinking metal Fe-Pt in a pressure transfer chamber 7 which shrinks as the temperature of a pressure transfer liquid 6 is raised. The heat shrinking rate of the heat shrinking body (bush) 10 is equal to the thermal expansion coefficient of the pressure transfer liquid 6. In the sensor of this constitution, the volume of the pressure transfer liquid 6 is increased in accordance with the temperature rise in the periphery of the sensor, and consequently the volume of the bush 10 is decreased. The volumetric increasing amount of the pressure transfer liquid 6 in the pressure transfer chamber 7 is absorbed by the bush 10. Therefore, the sensor becomes hard to be influenced by the volumetric change of the pressure transfer liquid due to the ambient temperature change, so that the correct pressure can be detected.
