These sensors detect the pressure inside the spaceship, and this is monitored to ensure there are no breaches, even tiny, in the hull of the ship. Even tiny breaches in the hull, such as due to a nebula, a bad field of super-magnetic forces, major equipment failure, could have the potential of leading to a breach of the life support systems if the breach was not stopped. The pressure sensors are monitored through the ship’s security computer system, and changes are made to override settings if any breaches are detected. This could be the disengaging of the ship’s engines and/or a change in the hull’s magnetic pulse fields temporarily until the breach is fixed.
