Apparauts and Method for Determining and /or Monitoring Temperature

An apparatus for determining and/or monitoring at least one temperature, comprising:

• at least a first temperature sensor and a second temperature sensor;
• at least five electric lines;
• and
• at least one measurement transmitter, said at least one measurement transmitter has at least four terminals for electrical connection of said at least five electric lines to said measurement transmitter, wherein:
• said first temperature sensor is connected to at least three terminals of said at least four terminals of said measurement transmitter via at least three electric lines of siad at least five electric lines;
• said at least three electric lines are connected with said first temperature sensor and with said measurement transmitter in such a manner that, via a 3-line circuit, a value of electrical resistance of at least one of said at least three electric lines can be obtained;
• said second temperature sensor is connected with at least two terminals of said at least four terminals of said measurement transmitter via at least two electric lines of said at least five electric lines;
• and
• the value of electrical resistance of at least one electric line of said at least five electric lines obtained via said 3-line circuit serves for determining electrical resistance of at least one electric line of said at lest five electric lines, via which said second temperature sensor is connected with said measurement transmitter.
