ABSTRACT:
A device for providing remote indication of the opening of a weighted pallet type tank vent in which a permanent magnet is attached to the end of the pallet guide shaft distal to the pallet. A magnetic induction sensor is secured to the outside of the shaft guide to sense movement of the magnetic field produced by the magnet and produce an electrical signal which may be transmitted to a remote location to indicate that the pallet has opened and relieved pressure in the tank.
