1. Linear, gripping, or clamping device comprising a microprocessor, a basic housing, a linear, gripping, or clamping element detachably arranged on the basic housing, and at least two different sensor types arranged on the basic housing, wherein the at least two different sensor types are chosen from
a geomagnetic field sensor;
a gyro sensor, and
a magnetic field sensor sensing the position of a magnet and configured to detect information about a current magnetic field strength, wherein the microprocessor is configured to determine information about the current location of the linear, gripping, or clamping device depending on the detected current magnetic field strength,
wherein the microprocessor is configured to simultaneously merge output signals of the at least two different sensor types to form a merged signal and to identify information about an identification of the linear, gripping, or clamping device or of the linear, gripping, or clamping element depending on the merged signal,
wherein the microprocessor is configured to determine, depending on the merged signal, a rotary position of at least one rotary table rotatably arranged on the basic housing,
wherein the microprocessor is configured to determine an operating status of the linear, gripping, or clamping device depending on the merged signal, and
wherein the linear, gripping, or clamping device further comprises:
a magnet arranged on the basic housing which can be displaced relative to the basic housing, a current position of the magnet relative to the basic housing depending on the operating status of the linear, gripping, or clamping device, and the microprocessor is further configured to determine information about the operating status depending on a detected current position of the magnet relative to the basic housing,
the microprocessor is further configured to calibrate the magnetic field sensor or the gyro sensor depending on the merged signal.
