发明名称 Apparatus and method for determining and/or monitoring temperature
摘要 An apparatus and method for determining and/or monitoring at least one temperature, the apparatus including: a first and a second temperature sensor; a measurement transmitter; wherein the measurement transmitter has four terminals for electrical connection of electric lines; and five electric lines. The first temperature sensor is connected with three terminals of the measurement transmitter via three electric lines the three electric lines are connected with the first temperature sensor and with the measurement transmitter in such a manner that, via a 3-line circuit, a value of the electric resistance of at least one of the three lines can be obtained; and the second temperature sensor is connected with two terminals of the measurement transmitter via two electric lines. The value of the electrical resistance of the at least one electric line obtained via the 3-line circuit serves for determining the value of the electrical resistance of at least one electric line, via which the second temperature sensor is connected with the measurement transmitter.
