PURPOSE:To reduce ambient temperature compensating errors, by imparting elasticity to a temperature sensing tube so that the internal volume is changed by an internal pressure, in the expansion and contraction of fluid, which is sealed in a part from the temperature sensing tube to an actuator. CONSTITUTION:Fluid such as an organic liquid, which is expanded and contracted, is sealed in a temperature sensing tube 7 and a Bourdon tube 6. A pointer 3 is rotated by the temperature detection performed by the temperature sensing tube 7, and the temperature is indicated. Elasticity is imparted to the temperature sensing tube 7, so that the internal volume is changed by an internal pressure. Thus the temperature sensing tube 7 is made large, and ambient temperature compensating errors and reduced. |
