2. Pressure switch - Wikipedia

   en.wikipedia.org/wiki/Pressure_switch

   An electronic pressure switch incorporates some variety of pressure transducer (strain gauge, capacitive element, or other) and an internal circuit to compare the measured pressure to a set point. Such devices may provide improved repeatability, accuracy and precision over a mechanical switch.

3. Components of jet engines - Wikipedia

   en.wikipedia.org/wiki/Components_of_jet_engines

   The propelling nozzle converts a gas turbine or gas generator into a jet engine. Power available in the gas turbine exhaust is converted into a high speed propelling jet by the nozzle. The power is defined by typical gauge pressure and temperature values for a turbojet of 20 psi (140 kPa) and 1,000 °F (538 °C). [18]

4. Fuel gauge - Wikipedia

   en.wikipedia.org/wiki/Fuel_gauge

   The digital fuel gauge in a 2018 Mazda 3 showing a nearly-empty tank along with a distance to empty display. Typical old-style fuel gauge on a 50 ccm chinese-made scooter from 2008, with the internationally used pictogram of a gas pump. The system can be fail-safe. If an electrical fault opens, the electrical circuit causes the indicator to ...

5. Governor (device) - Wikipedia

   en.wikipedia.org/wiki/Governor_(device)

   A governor, or speed limiter or controller, is a device used to measure and regulate the speed of a machine, such as an engine.. A classic example is the centrifugal governor, also known as the Watt or fly-ball governor on a reciprocating steam engine, which uses the effect of inertial force on rotating weights driven by the machine output shaft to regulate its speed by altering the input flow ...

6. Aircraft engine controls - Wikipedia

   en.wikipedia.org/wiki/Aircraft_engine_controls

   This saves room on the instrument panel by negating the need for four different dedicated fuel gauges. Fuel select valve - Connects the fuel flow from the selected tank to the engine. If the aircraft is equipped with a fuel pump: Fuel pressure gauge - Indicates the supply pressure of fuel to the carburetor (or in the case of a fuel-injected ...

7. Pressure regulator - Wikipedia

   en.wikipedia.org/wiki/Pressure_regulator

   Two-gauge pressure regulator connected to gas cylinder used for breathing gas supply. Pressure regulators are used with diving cylinders for Scuba diving. The tank may contain pressures in excess of 3,000 pounds per square inch (210 bar), which could cause a fatal barotrauma injury to a person breathing it directly. A demand controlled ...

8. American Automobile Association - Wikipedia

   The American Automobile Association (AAA) was founded on March 4, 1902, in Chicago, Illinois, in response to a lack of roads and highways suitable for automobiles. [4] [5] At that time, nine motor clubs with a total of 1,500 members banded together to form the AAA.

9. Alternator - Wikipedia

   en.wikipedia.org/wiki/Alternator

   In what is considered the first industrial use of alternating current in 1891, workers pose with a Westinghouse alternator at the Ames Hydroelectric Generating Plant.This machine was used as a generator producing 3,000-volt, 133-hertz, single-phase AC, and an identical machine 3 miles (4.8 km) away was used as an AC motor.
