摘要：
A position measuring device including a scale carrier member and a scanning device for scanning the scale. A temperature difference is generated between the scale carrier member and/or the scanning device, on the one hand, and a housing surrounding the scale carrier member and the scanning device, on the other hand. The temperature difference ensures that condensate is always precipitated on the colder housing.
