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

A survival suit (or more specifically an immersion survival suit), is a special type of waterproof dry suit that protects the wearer from hypothermia from immersion in cold water, after abandoning a sinking or capsized vessel, especially in the open ocean

A detecting element that is intended to sense proximity.

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

A pressure vessel located in both pump- and compressor piping systems in order to reduce residual pulsation fluctuations, as a result of discontinue operation effects, within an allowable level specified.

A physical object that adds or removes mechanical energy to a fluid, either constantly or periodically.

Is a modular frame containing a pump system and its associated components.

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

A mechanical structure intended to receive a number of pieces of basically standardized modular equipment.

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 personal radiation monitor is a device that detects the presence of any radiation sources.

Is a heat exchanger which cools a fluid and heats the surrounding environment.

A mobile radio communications centre.

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

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

A signal at a railway grade crossing that indicates the approach of a Locomotive.

A safety system to govern the use of single rail tracks to ensure only one locomotive can use the track at any one time. The rail key token station controls the issue of key tokens permitting movement.

A physical object that consists of two parallel steel rails, generally anchored perpendicular to beams or railroad ties of timber, concrete, or steel to maintain a consistent distance apart, to facilitate transport on the rails with vehicles arranged in a train without the need for steering.

A detectable transmitted energy (e.g. voltage, current, pneumatic or magnetic field strength) by which information can be transmitted.

Is a civil structure and mechanical system built to collect, store, and utilize stormwater or surface runoff.

A sloping surface joining two different levels, as at the entrance or between floors of a building.

A positive displacement compressor in which forced reduction of gas volume takes place by the movement of a displacing element in a cylinder or enclosure.

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 instrument that records values represented by the input signal(s).
