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 pilot switch whose function is controlled by variations of temperature and whose contacts make or break automatically a load circuit when the temperature of the ambient space in which its sensing element placed or the temperature of the surface on which it is fixed reaches a predetermined value.
