A ventilator is a machine designed to mechanically move breathable air into and out of the lungs, to provide the mechanism of breathing for a patient who is physically unable to breathe, or breathing insufficiently.

A pipe or tube that has a constriction with a relative long passage with a smooth coned entry and exit.

A container intended for storage and/or processing of fluids.

Is a mechanical screening device used to separate materials by particle size through the use of a mesh screen and a vibrating motion.

A detecting element that is intended to sense mechanical vibration and in which the oscillating motion is transferred into a voltage or current signal.

A switch intended to give a on/off signal when vibration level have reached a pre-set value.

A transmitter of which the output is proportional to a measured vibration.

A type of portal designed to enable a safe but limited view into a hazardous area.

An analysing instrument intended to determine the viscosity of a fluid.

A regulator designed to automatically maintain a constant voltage level.

A signal converter that is intended for converting an input voltage signal into an output current signal.

An instrument transformer in which the secondary voltage, in normal conditions of use, is substantially proportional to the primary voltage and differs in phase from it by an angle which is approximately zero for an appropriate direction of the connections.

A transmitter which output is relative to a measured voltage.

A flow meter that measures the velocity of a fluid in a pipe by detecting the frequency of vortices being shed from a specially shaped obstructing element in the fluid stream.

A transmitter specially designed to convert the signal in a vortex flow meter into a standardized output signal.

A wafer pattern valve that is a check valve with a wafer pattern valve body.

Is a detector to detect metal that passes through it.

Which is flat and typically vertical suitable for separation.

Is a type of valve designed to be used at the lowest point of a water system or pipeline to allow for drainage and removal of sediment.
