Connecting with a coupling or coupler.

A lifting appliance that is a tower or derrick equipped with cables and pulleys that can lift or lower and move loads in multiple directions.

A block with a hook for use with a crane.

A mill that uses pressure or impact to reduce the particle size of solid materials.

Structure to allow water or a pipeline to pass under a road/railway through a pipe or concrete tube. Typically if span greater than 12ft (3.7m) then structure is a bridge

A signal converter that is intended to convert one current signal to another current signal.

A signal converter that is intended to convert an analogue signal (4 - 20 mA) to a proportional linear pneumatic output signal.

A signal converter that is intended to convert a current input signal to a proportional voltage output signal.

An instrument transformer in which the secondary current, in normal conditions of use, is substantially proportional to the primary current and differs in phase from it by an angle which is approximately zero for an appropriate direction of the connections.

A transmitter that transmits an analogue electrical current.

A physical object that is an instrument, machine, machine part, or tool that cuts.

A device that damps, typically a valve or plate (as in the flue of a furnace) for regulating the draft, or a device to stop vibration, typically a shock absorber or snubber.

A physical object intended to carry the load of equipment that is regularly lifted or launched, like a life boat, or of equipment that regularly is removed for inspection or maintenance, such as covers, hatches, etc.

a device that is used for the removal of dissolved gases like oxygen from a liquid. A deaerator plant

Is a vessel used to separate two or more components of a liquid solution by allowing the layers to settle according to density differences and then draining off the top layer while retaining the bottom layer.

An artefact that is used to control fibrillation of the heart.

A device that removes air or gases (methane, H2S, CO2 and others) from drilling liquids.

A piece of equipment specifically designed to remove moisture from air.

A filtration device used to purify tap water. They are normally composed of various resins that replace positive & negatively charged ions.

A control valve that is intended to operate at high temperature, and admit water into a deluge system.

A physical object intended to catch fluid droplets.

An analysing instrument intended to determine the density of a substance.

A device that provides a safe and rapid method of descent in case of an emergency situation requiring evacuation.

A physical object that is the primary element of a measuring chain which converts the input variable into a signal suitable for measurement.

A physical object that is an assembly of a sensing element and necessary ancillary devices making it able of detecting a state, e.g. pressure, temperature, or detect the presence of a selected substance, and produce a signal based on the detection.
