Abstract
PURPOSE: To enable detection of damage of a pressure reception diaphragm, by providing the third transmission medium between a measured medium and the first transmission medium.
CONSTITUTION: A diaphragm 20 for enclosing the third transmission medium 21 different from a measured medium Na and the first transmission medium NaK is provided between a pressure reception diaphragm 12 and the first transmission medium NaK. Mercury, which drastically reacts with sodium and then solidifies, or the like is used as the third transmission medium 21. If the pressure reception diaphragm 12 is damaged, the mercury reacts with the sodium and then solidifies. As a result, the pressure reception diaphragm 12 and the diaphragm 20 do not respond to the pressure of the sodium and the output of a pressure converter 18 connected to the diaphragms through the second transmission medium 16 becomes abnormal. Therefore, the damage of the pressure reception diaphragm 12 can be detected.
