A pilot switch the actuating system of which is operated by a moving part of a machine, when this part reaches a predetermined position.

A transmitter that is producing a standardized output signal dependent of a received input signal from a position detector.

A handheld or fixed device designed to identify and record the location of an object on the earth's surface. GPS, GALILEO, SYLEDIS, HYPERFIX, LORAN-C, DECCA etc. are all brands and working on different networks.

Elements like impellers rotating by the pressure of the fluid in a closed conduit to measure the flow of a liquid.

A flow transmitter specially designed to convert the signal from a positive displacement flow meter into a standardized electrical output signal.

An analysing instrument intended to determine the pour point of a fluid, i.e. the lowest temperature at which an oil or other liquid will pour under given conditions.

A device that removes voltage spikes from an AC or DC electrical supply.

A physical object intended to supply electric power according to specified levels and tolerances.

A detecting element intended to sense pressure.

A gauge intended to measure and display a representation of a measured pressure.

A regulator that is controlling/regulating the pressure in a system.

A functional switch that (usually) turns an electrical circuit on or off when the pressure level reaches a pre-set value.

A signal converter that is intended to convert a pressure input signal to DC output signal.

A non-corrugated plate heat exchanger that has flat plates with chemically etched flow passages which are diffusion bonded together into blocks.

Is a facility for measure & control, including the main plant computerized operational system, where all process, utility and off site activities are monitored. The system may be located in the main control room. (e.g. PLC Programmable logic controller, DCS distributed control system, ENMC Electrical Network Monitoring and Control system).

A measuring relay that, either solely or in combination with other relays, is a constituent of a protection equipment.

A detecting element that is intended to sense proximity.

A position switch that is operated without mechanical contact with the moving part.

Is an alarm system.

A manual control switch that is intended to switch when you push or touch the button.

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.

An element intended to determine a level based on high frequency electromagnetic waves.

A level transmitter that is producing a standardized electrical output signal based on the input signal from a radar type level sensor.

A radio transmitter, usually non-directional, that emits identifiable signals intended for radio direction-finding.

A transceiver which has the methods of signalling through space, without connecting wires.
