Millivolt thermostat mechanism The illustration is the interior of a common two wire heat-only household thermostat, used to regulate a gas -fired heater via an electric gas valve. Similar mechanisms may also be used to control oil furnaces, boilers, boiler zone valves , electric attic fans, electric furnaces, electric baseboard heaters, and ...
An automotive wiring diagram, showing useful information such as crimp connection locations and wire colors. These details may not be so easily found on a more schematic drawing. A wiring diagram is a simplified conventional pictorial representation of an electrical circuit. It shows the components of the circuit as simplified shapes, and the ...
A thermocouple, also known as a "thermoelectrical thermometer", is an electrical device consisting of two dissimilar electrical conductors forming an electrical junction.A thermocouple produces a temperature-dependent voltage as a result of the Seebeck effect, and this voltage can be interpreted to measure temperature.
A typical one-line diagram with annotated power flows. Red boxes represent circuit breakers, grey lines represent three-phase bus and interconnecting conductors, the orange circle represents an electric generator, the green spiral is an inductor, and the three overlapping blue circles represent a double-wound transformer with a tertiary winding.
I think you need to draw yourself a diagram. Draw the iron wire. Draw the copper wire. Connect them at one end of your diagram to create the hot-side thermocouple. Now figure out how you connect the wires at the other side of your diagram to create a complete circuit. Atlant 11:09, 3 August 2005 (UTC)
Converted to 660 V (later 750 V) DC third-rail supply 8 kV: 25 Hz Germany: Karlsruhe: Alb Valley Railway: 1911–1966, today using 750 V DC 10 kV Netherlands: The Hague – Rotterdam: Hofpleinlijn: from 1908, in 1926 converted to 1,500 DC, In 2006 replaced by 750 V DC light rail 10 kV: 50 Hz Russia: industrial railways at quarries Russian Railways
Sometimes true point-to-point wiring—without terminal strips—with very short connections, is still used at very high radio frequencies (in the gigahertz range) to minimise stray capacitance and inductance; the capacitance between a circuit-board trace and some other conductor, and the inductance of a short track, become significant or ...
This regulation is now carried out by an internal thermostat. Conveniently, both the sensing element of the thermostat and its control valve may be placed at the same location, allowing the use of a simple self-contained non-powered thermostat as the primary device for the precise control of engine temperature.
