A physical object that is a circular plate with no central opening and holes to match mating flanged ends. It is also equipped with a handle.
A physical object used in or in connection with a piping system.
A heat exchanger using plates as the device for separating the two fluids and across which the energy is transferred.
A physical object that adds or removes mechanical energy to a fluid, either constantly or periodically.
An electric converter for converting an alternating current into a direct current.
An electric signal transducer that is intended to convert one type of standardized transmission signal into another.
A ring of conducting material which is attached to and rotates with a shaft, so that the electric current may be transferred to a stationary circuit through a fixed brush pressing against it.
A valve that has linear action which is fitted with a solenoid for quick operation.
A filter that is separating solid particles from a fluid by passing the fluid through a wire mesh, screen or metal plates containing perforations or slits.
A switchgear and controlgear bearing a set of switches for connecting and disconnecting the various circuits of an electrical system, as of a telegraph, telephone, etc.
A physical object that is a general term covering switching devices and their combination with associated control, measuring, protective and regulating equipment, also assemblies of such devices and equipment with associated interconnections, accessories, enclosures and supporting structures.
A transformer that, by electromagnetic induction, transforms a system of alternating voltage and current into another system of voltage and current usually of different values and at the same frequency for the purpose of transmitting electrical power.
An ac power supply unit that maintains a continuous supply of electric power to the equipment it protects.
A circuit-breaker in which the contacts open and close within a highly evacuated envelope.
A container intended for storage and/or processing of fluids.
Is a mechanical screening device used to separate materials by particle size through the use of a mesh screen and a vibrating motion.
