Abstract
A position encoder is used to measure the position of two objects which are movable relatively to one another, and, for this purposes, includes a position-detection arrangement via which positional data are generated. In addition, the position-measuring device has at least one temperature sensor, which is used for measuring the temperature at at least one measuring point of the two objects, which are movable relative to each other, and for generating temperature data. The temperature sensor is configured as an infrared sensor which measures in a contactless manner and may be mounted in a housing of the position encoder. The position encoder is used, for example, in conjunction with an electric drive.
