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.
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 ...

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 ...
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]
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 ...
The Model AA Ford is powered by the same 201-cubic-inch (3.3 L) I4 engine that the Model A Ford used. The engine produced a maximum of 40 horsepower at 2,200 rpm.The engine featured an up-draft carburetor, six-volt generator, 2 and 4-blade fan, mechanical water pump, mechanical oil pump, electric starter and four-row radiator.
Another method of air-starting an internal combustion engine is by using compressed air or gas to drive a fluid motor in place of an electric motor. [3] They can be used to start engines from 5 to 320 liters in size and if more starting power is necessary two or more motors can be used.
