A piping assembly intended to transport exhaust gas or steam.

A physical object that is intended to deliver or exhaust volumes of vapour or gas at low differential pressure.

Is a fired heat transfer equipment intended to burn fuel and to transfer the heat of combustion to a liquid without vapourizing the liquid.

A detector that is intended to sense a flame.

A specially designed switch with connections for inputs from multiple flame detectors. The switch has a built in logic to determine the presence of a flame based on these inputs.

An analysing instrument intended to determine the flash point of a substance.

A projector providing a beam of intense illumination.

A detecting element that is producing a signal that is proportional to a flow rate.

A gauge intended to indicate a liquid or gas flow.

A regulator that normally use the differential pressure principle across an orifice to control the valve trim and regulate flow.

A functional switch that is intended to give a signal when the flow have reached a pre-set value.

A totalizer that adds up flow measurements.

A flow transmitter providing an output signal that is proportional to the flow inputs from a flow element.

A device capable of detecting droplets of water vapour suspended in the air near the ground.

A vehicle with power operated prongs that can be raised and lowered by will, for loading, transporting and unloading goods; chiefly used in factories and warehouses.

An analyser intended to determine the freezing point of a liquid.

A signal converter that is intended to convert a frequency or rotational speed input signal into a 0 - 20 mA or 4 - 20 mA current output signal.

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

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

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

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

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