A thermopile is an electronic device that converts thermal energy into electrical energy. It is composed of several thermocouples connected usually in series or less commonly, in parallel. Thermopiles are used for contactless temperature sensing. The function of a thermopile is to transfer the heat radiation emitted from the object to a voltage output. The output is in the range of tens or hundreds of millivolts.
The relation between electric intensity E, voltage applied V and the distance d between the plates of a parallel plate condenser is given by: V = E*L E = V/L
Volatility is a statistical measure of the dispersion of returns for a given security or market index. Analysis of a mineral oil sample for volatile compounds provides an indication of whether a fault or significant degradation has occurred.
