Abstract: An encoder system has a reading head and a material measure. The reading head has at least one first position sensor and at least one second position sensor. The position sensors are positioned at a fixed distance from one another in a reading direction. The material measure has a longitudinal direction and a transverse direction. The material measure has a first code segment in the longitudinal direction with a first absolutely coded code track. The reading head and the material measure are positioned relative to one another in such a way that the reading direction corresponds to the longitudinal direction. The reading head and the material measure are movable relative to one another in the reading direction. A first sensor position on the material measure can be detected by the first position sensor and a second sensor position can be detected on the material measure by the second position sensor.

Abstract: A device for measuring a change in length has a first fastening element, a second fastening element and at least one length element which is arranged between the two fastening elements. The one length element has a first end a second end and a length along a longitudinal direction. A force acting parallel to the longitudinal direction leads to a change in length of the length element. A lever element has a first end, a second end, and a fulcrum and is arranged transversely to the longitudinal direction. The lever element includes a first lever arm with a first length between the fulcrum and a first lever arm end and a second lever arm with a second length between the fulcrum and a second lever arm end, with the second length being greater than the first length.
