Is a communication system.
A current limiter that limits the power (energy) which can be delivered from a safe area into a hazardous area.
A control panel with an array of systematically arranged (piano like) keys by which a machine is operated or by which an instrument can be played on.
A lightning arrestor is a device used on electric power systems and telecommunication systems to protect the insulation and conductors of the system from the damaging effects of lightning.
Short for modulator/demodulator. A communications device that converts one form of a signal to another that is suitable for transmission over communication circuits, typically from digital to analogue and then from analogue to digital.
A switchgear and controlgear that houses motor starters to control electric motors.
A very accurate flow meter used to record oil exports.
A post or buoy placed over a shoal or bank to warn vessels, also a signal mark on land.
Equipment which projects an image on a screen by passing light through a transparent slide or other transparency.
Is an alarm system.
A physical object for detecting the presence of objects at a distance, or ascertaining their position or motion, by transmitting short radio waves and detecting or measuring their return after being reflected.
A radio transmitter, usually non-directional, that emits identifiable signals intended for radio direction-finding.
Is a piece of hardware intended to read and decode information encoded on a carrier.
A positive displacement pump which contains a displacing element intended to be moved in a reciprocating movement to exert pressure on a fluid, typically moving within a cylindrical space.
A process control unit that can be operated in remote.
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 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 system that provides voice and telefax communication via satellites.
A physical object that is capable of receiving a signal and where the signal can be stored, recorded or converted into a useful form.
A device with one input and at least two outputs used for dividing a detectable transmitted energy (as a voltage, current, or magnetic field strength) by which information can be transmitted.
Device which separates oil from water by mechanically wipe the oil of the water surface.
A detecting instrument that is intended to measure the upload and download speed of an internet connection.
A device that transfer data between a computer and a magnetic tape.
In a communications network, a network node equipped for interfacing with another network that uses different protocols.
A transceiver that transmits a signal automatically in response to an appropriate triggering signal.
