A circuit-breaker in which the contacts open and close in oil.

A mist detector that is intended to detect oil mist.

An element designed to measure an oxidation reduction potential (ORP).

One-way communications device in which the intended receiver is alerted to receive a message or return a phone call.

An internal combustion engine that is an induction compression ignition exhaust engine which ignites a petrol air mixture with an electric spark.

An analysing instrument intended to measure, indicate and/or produce a signal which represents the measured alkalinity / acidity in a fluid or matter.

An element designed to measure pH (potential of Hydrogen).

A detector that is intended to detect a pig inside the pipeline or pig receiver.

A transmitter intended to detect a pig passage and transmit a signal representing the measured value.

A differential pressure flow meter utilizing a pitot tube (a probe with an open tip) that is inserted into the flow field.

A heat exchanger using plates as the device for separating the two fluids and across which the energy is transferred.

A control valve that is also a plug valve and an actuated valve.

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.

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.
