The thermocouple sensor detects the heat from the pilot light and sends a signal to keep the gas valve open, but if the pilot light is extinguished, then the thermocouple will send a signal to the ...
A pilot light is a small gas flame, usually natural gas or liquefied petroleum gas, which serves as an ignition source for a more powerful gas burner. Originally a pilot light was kept permanently alight, but this wastes gas. Now it is more common to light a burner electrically, but gas pilot lights are still used when a high energy ignition ...
For gas appliances, a flame supervision device (FSD) – alternative name: flame failure device (FFD) – is a general term for any device designed to stop flammable gas going to the burner of a gas appliance if the flame is extinguished. This is to prevent a dangerous buildup of gas within the appliance, its chimney or the room. [1]
Wand lighter. A gas lighter is a device used to ignite a gas stove burner. It is used for gas stoves which do not have automatic ignition systems. It uses a physical phenomenon which is called the piezo-electric effect to generate an electric spark that ignites the combustible gas from the stove’s burner.
Gas stoves today use two basic types of ignition sources, standing pilot and electric. [21] A stove with a standing pilot has a small, continuously burning gas flame (called a pilot light) under the cooktop. [21] The flame is between the front and back burners. When the stove is turned on, this flame lights the gas flowing out of the burners.
Hotpoint continued as a subsidiary of GEC until 1989, when it was merged into a new division of GEC called General Domestic Appliances (GDA). 50% of GDA was purchased by General Electric (USA), with whom it owned the joint venture. In 1998, the Redring and Xpelair brands also joined GDA, and Hotpoint was categorized as part of GDA Applied Energy.

PFD with key instrument displays labelled PFD of a Garmin G1000. The details of the display layout on a primary flight display can vary enormously, depending on the aircraft, the aircraft's manufacturer, the specific model of PFD, certain settings chosen by the pilot, and various internal options that are selected by the aircraft's owner (i.e., an airline, in the case of a large airliner).
