Linearization of Resistance Thermometers and Other Transducers

摘要: Given a resistive transducer which responds directly or indirectly to physical quantity x, it is shown that the relationship may be linearized by linear methods if and only both resistance conductance of are concave upward as functions x. This result applies either deflection output null balance output. The application common temperature transducers considered. It thermistors, metals (e.g., copper), nickel can in terms temperature, but platinum cannot be. If linearization desired reciprocal absolute then all above mentioned linearized, including platinum. Quantitative results obtained for cases.
