An abridged text of a report on design and characteristics of a new three-lead temperature- current sensor with application of parametric bandgap-calibration is presented. The main distinction of the sensor consists of its output characteristic's zero coincidence with Celsius scale zero. Those fields of the sensor application are considered which are realized in a more complicated way from the point of view of circuitry and are of poorer quality in case of two- lead sensor analogs of a PTAT type (proportional to absolute temperature). Functionality of the proposed thermosensor is considerably widened.
