Casing vent security device |
摘要 |
A casing vent security device includes an in-line section in communication with a casing vent, the in-line section having an ambient air passageway for selectively allowing ambient air to pass through the in-line section and into the vent. The device further includes a plurality of sensors disposed within the in-line section for monitoring the ambient air passing through the in-line section. The device still further includes at least one mechanism for selectively occluding the passage of ambient air into the vent upon receiving a signal from the sensors. The device provides information on the plurality of sensors and the vent.
