The pressure-resistant explosion-proof monitor and pressure-resistant explosion-proof container

摘要

PROBLEM TO BE SOLVED: To provide a flame-proof monitoring apparatus in which mount positions of a flame-proof microphone, a flame-proof camera, a flame-proof antenna and the like can be changed easily, without causing such a change that a corresponding qualification test should be executed again, and to provide an abnormity monitoring system using the flame-proof monitoring device.;SOLUTION: The flame-proof monitoring apparatus comprises: a flame-proof enclosure 26 having a flame-proof construction which contains at least an electric circuit, and having a mount section 28 which is disposed on at least either its upper surface side or lower surface side; a support body 22 which is mounted on the mount section of the flame-proof enclosure; and the camera, the microphone and the antenna which are supported by the support body 22. When changing the positions of the microphone, the camera, the antenna and the like, mount holes which are used for mounting the microphone, the camera, the antenna and the like on the support body, can be changed, thereby requiring no change in the flame-proof enclosure. Therefore, the mount positions of the microphone, the camera, the antenna and the like can be changed easily, without causing such the change that the qualification test should be executed again.;COPYRIGHT: (C)2007,JPO&INPIT
