An electric signal transducer that is intended to convert one type of standardized transmission signal into another.

A conveyor consisting of a series of slats generally made of metal or wood attached to an endless chain.

A slide 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 ring of conducting material which is attached to and rotates with a shaft, so that the electric current may be transferred to a stationary circuit through a fixed brush pressing against it.

A physical object that consists of wedge-shaped pieces of metal loosely joined together and fitted into a bushing to support a string of pipe. The slips have gripping elements to prevent the pipe from slipping down the drilling hole.

A detector that is intended to sense smoke.

A panel and a photovoltaic module whose main parts are solar cells.

A valve that has linear action which is fitted with a solenoid for quick operation.

An analyser intended to determine a mixture of solid particles in liquids or solid or liquid droplets in air.

A device decreasing noise in a HVAC system.

A meter intended to measure a sound pressure level.

An analyser intended to determine specific gravity's of materials. Typically of liquids.

A detecting instrument that is intended to measure the upload and download speed of an internet connection.

A switch intended to give a on/off signal when the speed have reached a pre-set value.

A transmitter that is producing a standardized output signal dependent of a received input signal from a rotational speed sensor.

A physical object that is intended to mix fluid by means of diverging the flow with static obstacles or by increasing locally the velocity.

A thermodynamic turbine in which steam is made to do work by expanding so as to create kinetic energy by acting on moving blades attached to a disc or drum.

An electrical connector capable of withstanding submersion to a specified depth.

A physical object that is protecting against a large but momentary increase in the voltage of an electric circuit.

A switchgear and controlgear bearing a set of switches for connecting and disconnecting the various circuits of an electrical system, as of a telegraph, telephone, etc.

A physical object that is a general term covering switching devices and their combination with associated control, measuring, protective and regulating equipment, also assemblies of such devices and equipment with associated interconnections, accessories, enclosures and supporting structures.

An instrument panel dedicated to a particular system.

A physical object that converts sound signals into corresponding variations of electric current (or potential), which is transmitted by wire or radio to a distant point where it is reconverted into sound.

A detector intended to detect temperature.
