Galvanic isolation is the principle of isolating functional sections of electric systems so that charge-carrying particles cannot move from one section to another.

A chromatograph where gas is injected directly into one or more separation columns.

An analyser which analyses the composition of gaseous mixture with two or more components.

A static device generating centrifugal force from an incoming flow which separates solid or liquids from a gas of a different density.

A detector that is intended to sense the presence of a specified concentration of a gas.

A distributor intended to distribute or redistribute a vapour.

An internal combustion engine that is a reciprocating engine in which gaseous fuel is mixed with air to form a combustible mixture in a cylinder which is fired by spark ignition.

A chromatograph where a liquid sample is injected and evaporated and subsequently carried to one or more separation columns.

A turbine that compresses air which is then mixed with fuel for combustion and expansion through a turbine section to generate relatively high power output for either mechanical drive or power generation.

A circuit-breaker in which the arc develops in a blast of gas.

A seal that is one or more closed loops of deformable material used between mating surfaces which have only very limited movement relative to each other.

A control valve that is a gate valve and an actuated valve.

A valve that is a valve where the closure member is a gate or disc with a linear motion parallel, or nearly parallel, to the plane of flat seats, which are transverse to the direction of flow.

A detecting instrument that is used for measuring or testing.

A physical object that is a casing with an arrangement of two or more gear-wheels transmitting rotating motion from the input shaft to the output shaft.

A process instrument that records values represented by the input signal(s).

A control valve that is a globe valve and an actuated valve.

A valve that is a valve where the closure member is a disc or piston operating with linear motion normal to the flat or shaped seat.

A separator that is based on the difference in specific gravity for the substances to be separated.

A system that injects grease for lubrication or sealing.

Is a plumbing fixture or vault installed in the wastewater drainage system to intercept and remove fats, oils, and greases.

Is a framework of metal bars or wire which is placed in front of something. Often a terminal unit for delivering supply air to a room or for collecting extract air from a room.

An artefact which is intended to wear down, polish, or sharpen by the abrasive action of a high-speed grinding wheel or disc.

Barrier material used to prevent moisture transmission.
