An attenuator is a telecommunication device that reduces the amplitude of a signal without appreciably distorting its waveform. Attenuators are usually passive devices. The degree of attenuation may be fixed, continuously adjustable, or incrementally adjustable.
An automatic tracking system used on ships and by vessel traffic services (VTS) for identifying and locating vessels.
A physical object intended to compress and supply air or gas at medium pressure and medium volume flow.
A unit or assembly of units or sections and associated fittings forming a rigid structural system used to securely fasten or support cables and raceways.
A physical object that uses centrifugal force to separate phases of different densities.
Any mechanical or electrical device that transmits or modifies energy to perform or assist a cleaning operation in the performance of human tasks.
A mill that uses pressure or impact to reduce the particle size of solid materials.
A device that removes air or gases (methane, H2S, CO2 and others) from drilling liquids.
A physical object intended to catch fluid droplets.
A physical object that contains a diverging channel-shaped chamber in which part of the kinetic energy of the fluid is converted into pressure energy.
An electric generator for the production of direct current and voltage.
A device used to translate print media into computer language so that a document can be viewed and read later on.
A drier is a physical object that is intended to remove absorbed or adsorbed liquid or water vapour below saturation state.
A power transformer of which the magnetic circuit and windings are not immersed in an insulating liquid.
A form of suction pump; a device using a high pressure jet of water to create partial vacuum at an intake opening to draw liquid from a sump.
A 'control panel' intended for electrical apparatus.
An electrical conductor that has several power distribution points.
A separator intended to separate material from a solution or suspension by electrostatic charge.
A radio beacon in the mobile service the emissions of which are intended to facilitate search and rescue operations (EPIRB).
A physical object that is intended to form material by forcing it in liquid phase through a shaping die by applying pressure and fix the form in the solid phase.
Machine capable of transmitting written input via telephone lines.
A closed transport device that is a gathering line tied into a trunk line.
A projector providing a beam of intense illumination.
A physical object that is intended to induce a reaction in a process fluid by heating it.
An electromagnetic storage device, continuously available within a computer system.
