Abstract
PURPOSE: To prevent occurrence of errors in zero point and span due to the residual bubbles, thermal expansion and contraction at the time of sealing a primary pressure transmission medium by providing a heater capable of controlling the temperature at the outer wall part of the pressure receiving part.
CONSTITUTION: The temperature of a pressure receiving part 1 due to a high temperature fluid such as liquid metal sodium of a coolant of an FBR is measured by a thermocouple 15, and a heater 14 extending from the pressure receiving part 1 to the first pressure transmitting medium chanber 5 is fed back and controlled. Consequently, the inner part of the chamber heated by a heater 14 to a high temperature is made vacuous, and impurities such as adsorptive gas and the like are purified. Thereafter, when NaK6 of the primary pressure transmitting medium 6 are sealed in the chamber 5 via an inlet port 10 and an output port 11, bubbles do not remain at the time of sealing of the medium 6, thermal expansion or contraction due to the temperature difference do not occur, and hence a pressure measurement free of zero point and span errors can be performed with a high precision.
