Zusammenfassung:PROBLEM TO BE SOLVED: To safely, securely and accurately acquire monitoring data in a pressure vessel, and to perform a further proper operation.SOLUTION: In this monitoring device for monitoring the inside of a spiral membrane pressure vessel which comprises a spiral membrane 28 in a pressure vessel 14, the monitoring device of the spiral membrane pressure vessel 14 has a facility for desalinating pressurized supply water by the spiral membrane 28. The monitoring device also comprises an in-pressure vessel sensor 36 which is arranged outside a collecting pipe 16, and monitors a pressurized part of the pressure vessel 14, and a signal line 26 which is connected from an end face of the pressure vessel 14, and arranged so as to penetrate the inside of the collecting pipe at a center of the spiral membrane toward the outside.SELECTED DRAWING: Figure 1 【課題】圧力容器内部のモニタリングデータを安全に安心してかつ高精度に取得することができ、より適切な運転を実現することを課題とする。【解決手段】本発明のスパイラル膜圧力容器内のモニタリング装置は、スパイラル膜28を圧力容器内14に備え、加圧した供給水をスパイラル膜28によって淡水化する設備のスパイラル膜圧力容器14のモニタリング装置において、集水管16の外側に配置され、圧力容器14の加圧部をモニタリングする圧力容器内センサ36と、圧力容器14の端面からつながり、スパイラル膜の中心部の集水管の内側から外側に貫通するよう配置された信号線26とを備えたことによって、上記課題を解決する。【選択図】図1
