The invention relates to an offset regulation device for a sensor module and a method for realizing such an offset regulation, particularly for acceleration sensors and pressure sensors. The disadvantage of currently used offset regulation devices is that impermissible offset drifts or other errors are not recognized and are camouflaged by the offset regulation device. As a result, the measuring values can be distorted. The offset regulation device according to the invention comprises a monitoring device that is integrated into the offset regulation device and which recognizes and indicates such errors. This monitoring device comprises an analog or digital adder, which detects the deviation of the actual value from the desired value or values depending thereon. If the regulation takes too long because the deviation is too large and the offset is therefore not permissible, then a maximum or minimum value is reached during the adding up in the adder. Once a limit value is reached, an error message is generated and indicated.
