A physical object that is a closed, rigid box or casing used to enclose and protect the junctions of electric wires or cables.

A reboiler often boils liquid coming from the bottom of a distillation column, after which the resulting vapour is returned to the distillation column.

A physical object intended to produce an optical radiation, usually visible.

A functional switch that is intended to give an on/off signal when particulate material or fluid level have reached a pre-set value.

A detecting element intended to measure corrosion using electrical conductivity.

An analyser for liquid.

A detector which is capable of detecting selected types of liquids.

A transducer which produces a signal with a defined relationship to the force applied to it.

A physical object that is designed to load or unload products into or from vehicles, wagons or vessels at variable positions.

An electroacoustic transducer that converts an electric signal into sound.

A physical object that is an electric light and its fittings.

A level gauge that use a float containing a magnet to transfer information about its position to a indicator rail with white and red flaps mounted on the outside of the tube.

A level transmitter which uses a floater and magnetic contacts to measure and transmit level.

A manual call point is a device which enables personnel to raise an alarm in the event of a fire incident by pressing a frangible element to activate the alarm system.

A control switch that is operated by a person.

A switch which is operated by a person.

A mechanical controller that is intended to position a given item in accordance with a received input signal.

A switchgear and controlgear that houses motor starters to control electric motors.

An operated valve that is opened and closed with a motor.

An analyser giving as output a signal that represents more than one physical properties of the analysed substance.

A flow meter for the metering a mixture of two or more fluid phases.

A valve not designed to regulate flow (e.g. on/off). A valve with multiple orifices or flow-restriction device to control fluid flow. Includes an actuator that needs auxiliary power to operate.

A valve not designed to regulate flow (e.g. on/off). A multi port valve which has the possibility of multiple distinct paths for flow through it. Includes an actuator that needs auxiliary power to operate.

A needle valve that is equipped with an actuator that manipulates a stream of fluid in the response to a signal from an external sensing element and with input of energy from an external source.

A level transmitter that is producing a standardized electrical output signal based on the input signal from a nucleonic level detector.
