Compensator
Encyclopedia
Compensator can refer to:
  • Pressure control on a piston pump
    Piston pump
    A piston pump is a type of positive displacement pump where the high-pressure seal reciprocates with the piston. Piston pumps can be used to move liquids or compress gases.-Types:* Axial piston pump* Radial piston pump...

  • An alternative term for pipeline expansion joint
    Expansion joint
    An expansion joint or movement joint is an assembly designed to safely absorb the heat-induced expansion and contraction of various construction materials, to absorb vibration, to hold certain parts together, or to allow movement due to ground settlement or earthquakes...

  • A muzzle brake
    Muzzle brake
    Muzzle brakes and recoil compensators are devices that are fitted to the muzzle of a firearm or cannon to redirect propellant gases with the effect of countering both recoil of the gun and unwanted rising of the barrel during rapid fire...

    , used to counter the recoil of a firearm, or to prevent the muzzle from climbing due to kickback from the rapid firing of an automatic or semi-automatic weapon
  • A device that offsets or counterbalances a destabilising factor: See
    • Buoyancy compensator (diving)
    • Buoyancy compensator (aviation)
      Buoyancy compensator (aviation)
      The static buoyancy of airships during a trip is not constant. It is therefore necessary to take measures to control the buoyancy and thus the altitude, the so-called buoyancy compensation.-Changes which have an effect on buoyancy:...

    • Static VAr compensator
      Static VAr compensator
      A static var compensator is an electrical device for providing fast-acting reactive power on high-voltage electricity transmission networks. SVCs are part of the Flexible AC transmission system device family, regulating voltage and stabilising the system...

    • Heisenberg compensator
    • Lead-lag compensator
      Lead-lag compensator
      A lead–lag compensator is a component in a control system that improves an undesirable frequency response in a feedback and control system. It is a fundamental building block in classical control theory.- Applications :...

  • Motion compensator
    Motion compensator
    A motion compensator is a device that decreases the undesirable effects of the relative motion between two connected objects. Motion compensators are usually placed between a floating object and a more stationary object, such as a vessel or a structure fixed to the seabed. The motion compensator...

  • Optical compensator, also known as a wave plate
    Wave plate
    A wave plate or retarder is an optical device that alters the polarization state of a light wave travelling through it.- Operation :A wave plate works by shifting the phase between two perpendicular polarization components of the light wave. A typical wave plate is simply a birefringent crystal...

    or a retarder
