  2. Pressure switch - Wikipedia

    en.wikipedia.org/wiki/Pressure_switch

    Industrial pressure switches may have a calibrated scale and pointer to show the set point of the switch. A pressure switch will have a hysteresis, that is, a differential range around its setpoint, known as the switch's deadband, inside which small changes of pressure do not influence the state of the contacts. Some types allow adjustment of ...

    en.wikipedia.org/wiki/Switchgear

    High-voltage switchgear A section of a large switchgear panel. Tram switchgear This circuit breaker uses both SF 6 and air as insulation.. In an electric power system, a switchgear is composed of electrical disconnect switches, fuses or circuit breakers used to control, protect and isolate electrical equipment.

  4. Switch - Wikipedia

    en.wikipedia.org/wiki/Switch

    Switches can be designed to respond to any type of mechanical stimulus: for example, vibration (the trembler switch), tilt, air pressure, fluid level (a float switch), the turning of a key , linear or rotary movement (a limit switch or microswitch), or presence of a magnetic field (the reed switch). Many switches are operated automatically by ...

  5. Vacuum interrupter - Wikipedia

    en.wikipedia.org/wiki/Vacuum_interrupter

    In electrical engineering, a vacuum interrupter is a switch which uses electrical contacts in a vacuum. It is the core component of medium-voltage circuit-breakers, generator circuit-breakers, and high-voltage circuit-breakers. Separation of the electrical contacts results in a metal vapour arc, which is quickly extinguished.

  6. Reduced pressure zone device - Wikipedia

    en.wikipedia.org/wiki/Reduced_pressure_zone_device

    It is designed to handle the pressure fluctuations). In the case of the upstream check valve passing, the differential pressure (higher supply pressure compared with the lower chamber pressure) causes any flow to occur only in one direction. A buildup of pressure in the chamber in such a case would be relieved to the drain.

  7. Nozzle and flapper - Wikipedia

    en.wikipedia.org/wiki/Nozzle_and_flapper

    The example shown is pneumatic. At sub-millimeter distances, a small movement of the flapper plate results in a large change in flow. The nozzle is fed from a chamber which is in turn fed by a restriction, so changes of flow result in changes of chamber pressure. The nozzle diameter must be larger than the restriction orifice in order to work. [2]

    en.wikipedia.org/wiki/Diaphragm_(mechanical_device)

    It serves either as a barrier between two chambers, moving slightly up into one chamber or down into the other depending on differences in pressure, or as a device that vibrates when certain frequencies are applied to it. [1] A diaphragm pump uses a diaphragm to pump a fluid. A typical design is to have air on one side constantly vary in ...
