An authoritative collection of values with a relationship to instrumentation. The columns of this collection is specified and controlled.
A detector that is intended to sense smoke.
A valve that has linear action which is fitted with a solenoid for quick operation.
An analyser intended to determine a mixture of solid particles in liquids or solid or liquid droplets in air.
A meter intended to measure a sound pressure level.
An analyser intended to determine specific gravity's of materials. Typically of liquids.
A detecting instrument that is intended to measure the upload and download speed of an internet connection.
A switch intended to give a on/off signal when the speed have reached a pre-set value.
A transmitter that is producing a standardized output signal dependent of a received input signal from a rotational speed sensor.
A check valve that is a check valve where the closure member is a disc which swings freely on a hinge and which opens automatically when flow is established and closes automatically when flow ceases or is reversed.
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 physical object that converts sound signals into corresponding variations of electric current (or potential), which is transmitted by wire or radio to a distant point where it is reconverted into sound.
A detector intended to detect temperature.
A gauge that is intended to measure and indicate a temperature.
A regulator that is intended to keep a temperature within certain boundaries.
A functional switch that is intended to give an on or off signal when the temperature have reached a pre-set value.
A transmitter that is producing a standardized output signal dependent of a received input signal from a temperature element.
An 'artefact' intended for the termination of cables.
An analysing instrument that is intended to determine a physical property that is named thermal conductivity.
An element which uses the principle of thermal conductivity to measure volume flow rate.
A velocity flow meter which uses the principle of thermal conductivity to measure volume flow rate.
A pair of electrical conductors of dissimilar materials, joined at one end (the measuring or hot junction), which produces an electromotive force (e.m.f.) due to the Seebeck effect in a circuit formed by connecting the other ends of the dissimilar materials used (the reference or cold junction) to a device for measuring e.m.f. Def. acc. to IEC 902 1987.
A physical object that is a pressure-tight receptacle adapted to receive a temperature sensing element, provided with external threads or other means for pressure-tight attachment to a vessel or pipe.
A timepiece that measures a time interval and signals its end; a time-switch.
A transceiver that transmits a signal automatically in response to an appropriate triggering signal.
