Physical quantities, such as temperature, mechanical stress, gas concentration and acidity, can be measured by means of elements which generate an EMF as a function of the relevant quantity. In many cases the temperature dependence of the conversion is inconvenient. The proposed temperature correcting circuit considerably reduces the said temperature influence, at least for a given operating range, in that the temperature-dependent internal resistance of the element is measured or used by means of an alternating current and the EMF is corrected by means of this temperature information. |
