概要
Negative atmospheric pressure is an isolation technique used in nuclear facilities including vessels and hot-cells to prevent release of radioactive materials. In the related system, differential pressure switches are very important function for process monitoring such as liquid level and negative pressure in a reprocessing process. Although air-tight switches have been using to avoid radioactive contamination, such type of switch have not meet requirements for precise operation under deep negative pressure. Therefore, we have been investigation an improved types of switches to overcome the problem. We have developed a prototype switch and made some vibration and endurance tests. Their results are described in this paper.
