A semiconductor device having a resistance that decreases rapidly with an increase in temperature. It is used for temperature measurement, to compensate for temperature variations in a circuit.
A device for measuring temperature consisting of a pair of wires of different metals or semiconductors joined at both ends. The electromotive force generated depends upon the temperature difference.
An instrument that measures the rate of flow of a liquid or gas within a pipe or tube.
A pressure sensor measures pressure, typically of gases or liquids. Pressure is an expression of the force required to stop a fluid from expanding.
A device which can convert mass to electrical signal.
