An electric converter for converting an alternating current into a direct current.

An analyser intended to determine the oxidation and reduction capability of material.

A pressure transmitter where pressure is applied to one side of the sensor while the other side is open to atmosphere. The transmitter generate standardized output signal representing the measured value.

A physical object that can be any electrical device, usually incorporating an electromagnet, whereby a current or signal in one circuit can open or close another circuit.

A RTU, or Remote Terminal Unit is a device which interfaces objects in the physical world to a DCS or SCADA system by transmitting telemetry data to the system and/or altering the state of connected objects based on control messages received from the system.

A process control unit that can be operated in remote.

A temperature sensing element that operate on the principle of changes in electrical resistance of pure metals (sintered semiconductor material) and are characterized by an almost linear positive change in resistance with temperature.

A physical object that is a totally sealed, gas-insulated compact switchgear unit. The primary switching devices can be either switch disconnectors or fused switch disconnectors or circuit breakers.

A conveyor comprising a series of closely spaced rollers set so that their crests can support articles to be conveyed. They may be power-driven, or freely revolving. Tapered rollers are used to form bends in the conveyor line.

A positive displacement compressor in which compression displacement is effected by the positive action of rotating elements.

A positive displacement pump that consists of a chamber containing gears, cams, screws, vanes, plungers or similar elements actuated by relative rotation of the drive shaft or casing and which has no separate inlet and outlet valves.

A 'well drilling system' and an 'artefact' in which the torque is transferred to the drill string using rotary table and kelly.

A detecting element that is intended to sense rotational speed.

A router is a computer networking device that forwards data packets toward their destinations through a process known as routing. Routing occurs at layer 3 (Network layer) of the OSI seven-layer model.

A tool that can be used to install or remove machines or equipment.

A sample loop adds a predetermined volume to the process.

A physical object intended to be used to collect and contain representative specimens or selections.

A detector intended to detect sand in a fluid.

A system that provides voice and telefax communication via satellites.

Is a conveyer intended to move dry, solid material from one location to another by means of a helix or screw rotating in a cylindrical conduit.

A manual control switch which has more then two possible positioning states.

A valve that includes a means of operation (e.g. spring / gravity / fluid pressure / counter balance), and is not depending on an external source of energy.

A tank gauge that is intended to intermittently lower a displacer to measure a liquid level, bottom level, interface level or density.

A vibrating screen for sifting out rock cuttings from drilling mud.

A damper intended for closing off parts of a ventilation system.
