  2. Galvanometer - Wikipedia

    en.wikipedia.org/wiki/Galvanometer

    The taut-band movement is a modern development of the D'Arsonval-Weston movement. The jewel pivots and hairsprings are replaced by tiny strips of metal under tension. Such a meter is more rugged for field use.

  3. Multimeter - Wikipedia

    en.wikipedia.org/wiki/Multimeter

    The meter movement in a moving pointer analog multimeter is practically always a moving-coil galvanometer of the d'Arsonval type, using either jeweled pivots or taut bands to support the moving coil. In a basic analog multimeter the current to deflect the coil and pointer is drawn from the circuit being measured; it is usually an advantage to ...

  5. Variometer - Wikipedia

    en.wikipedia.org/wiki/Variometer

    Common types of variometers include those based on a diaphragm, a vane (horn), a taut band, or are electric based. The vane variometer consists of a rotating vane, centered by a coil spring, dividing a chamber into two parts, one connected to a static port, and the other to an expansion chamber.

  6. Ant on a rubber rope - Wikipedia

    en.wikipedia.org/wiki/Ant_on_a_rubber_rope

    An ant starts to crawl along a taut rubber rope 1 km long at a speed of 1 cm per second (relative to the rubber it is crawling on). At the same time, the rope starts to stretch uniformly at a constant rate of 1 km per second, so that after 1 second it is 2 km long, after 2 seconds it is 3 km long, etc.

  7. Tape correction (surveying) - Wikipedia

    en.wikipedia.org/wiki/Tape_correction_(surveying)

    C is the coefficient of thermal expansion of the metal that forms the tape; L is the length of the tape or length of the line measured. is the observed temperature of the tape at the time of measurement; is the standard temperature, when the tape is at the correct length, often 20 °C;

  8. Waveguide - Wikipedia

    en.wikipedia.org/wiki/Waveguide

    Electric field Ex component of the TE31 mode inside an x-band hollow metal waveguide. A waveguide is a structure that guides waves by restricting the transmission of energy to one direction. Common types of waveguides include acoustic waveguides which direct sound , optical waveguides which direct light , and radio-frequency waveguides which ...

  9. Cover meter - Wikipedia

    en.wikipedia.org/wiki/Cover_Meter

    A cover meter is an instrument to locate rebars and measure the exact concrete cover. Rebar detectors are less sophisticated devices that can only locate metallic objects below the surface. Due to the cost-effective design, the pulse-induction method is one of the most commonly used solutions. [1]
