Visual indication equipment operation

Electrically operated equipment comprising:—

• an environmentally sealed enclosure having at least one wall permeable to a magnetic flux;
• an electrically operated circuitry environmentally protected within the enclosure;
• a magnetic field generator within the enclosure and interconnected to the electrically operated circuitry for producing a magnetic flux indicative of a state of operation of the electrically operated circuitry, said magnetic flux to pass through the permeable wall;
• a magnetic flux sensor positioned outside the enclosure to be influenced by the magnetic flux, thereby to induce an electrical current corresponding to the magnetic flux;
• and
• a visual indicator positioned outside the enclosure and electrically connected to the sensor and controllable by the electrical current to produce a visual indication of the state of operation of the electrically operated circuitry.

A method of visually indicating an operational state of an electrically operated circuitry which is environmentally sealed within an environmentally sealed enclosure comprising:—

• producing a magnetic flux within the enclosure, the magnetic flux indicative of the state of operation of the electrically operated circuitry;
• passing the magnetic flux through a flux permeable wall of the enclosure, to the outside of the enclosure;
• and
• on the outside of the enclosure, sensing the magnetic flux, inducing the sensed flux into a corresponding electrical current and, with the electrical current, operating a visual indicator to indicate the state of operation of the electrically operated circuitry.
