ABSTRACT:
The invention relates to a device and a method for the contact-free measurement of rotary and/or linear movements of components moving in relation to one another; and a device for the contact-free measurement of rotary and/or linear movements of components moving in relation to one another utilizing a Giant Magnetic Resistor (GMR) cell and at least one magnetic element, and an evaluation unit, in which two delivery voltages with mirror-image profiles are generated by the magnet element, moved in relation to said GMR cell.
