Abstract

The present invention is directed to a device and system for monitoring the closure state of a hatch. A pressure sensor is positioned between the upper sealing ring of the hatch lid and the lower sealing ring of the flange, adjacent to or within the pressure gasket. In the open position, force sensor detects little force between the upper and lower sealing rings, in the closed position, the sensors detects an increase in force, but in the closed and latched position, the force sensor detects much higher force between the upper and lower sealing rings. The force sensor is electrically coupled to a monitor unit that communicates the force readings (either as raw or processed data) to remote locations such as data/processing remote centers, clouds, or portable devices. Cry-out alarms may be employed to alert operators when a hatch is open or not securely latched.
