Claim 0:
1. A current measuring transducer for measuring an electric current in an electrical conductor that can be arranged so as to extend through the current measuring transducer, comprising:
a housing, comprising:
a housing base portion and at least one housing mating portion which can be coupled with the housing base portion;
wherein, in a closed state, the housing base portion is coupled to the housing mating portion and a central through opening is defined, and wherein the electrical conductor can be arranged in the central through opening between the housing base portion and the housing mating portion so that the electrical conductor extends through the housing;
wherein the housing base portion comprises a first part of a probe ring and the housing mating portion comprises a second part thereof, so that in the closed state of the housing a closed loop probe ring is formed around the conductor when the conductor is arranged inside the current measuring transducer;

at least two sensors for simultaneously measuring the electric current in the electrical conductor and generating first and second sensor signals; and
an evaluation device in the current measuring transducer, the evaluation device comprising a microcontroller configured for simultaneously evaluating the first and second sensor signals and for outputting a corrected output signal,
wherein the housing base portion and the housing mating portion each have first and second probe ring end faces, wherein in the closed state of the housing, the probe ring end faces of the housing base portion and of the housing mating portion adjoin one another, and
wherein the probe ring defines first and second sensor accommodation areas on the probe ring end faces for receiving one or more sensors per probe ring face.
