Abstract
A device for determining the temperature of a tubular strand conveyed out of an extrusion device includes at least one temperature sensor configured to measure a first temperature of an outside of the tubular strand at a first position of the tubular strand. An evaluation apparatus further included and configured to compare the first temperature with a second temperature of the outside of the tubular strand at a second position of the tubular strand and determine at least one of a temperature within the tubular strand or a temperature on the inside of the tubular strand at a position of the tubular strand based on the comparison of the first and second temperature.
Claims27
A device for determining a temperature of a tubular strand conveyed out of an extrusion device, comprising:
- at least one temperature sensor configured to measure a first temperature of an outside of the tubular strand at a first position of the tubular strand, wherein the first temperature is measured after the tubular strand passes through a cooling section positioned downstream of the extrusion device;
- and
- an evaluation apparatus configured to,
- determine a difference between the first temperature and a second temperature of the outside of the tubular strand that taken at a second position of the tubular strand, wherein the second position is spaced apart from the first position along a conveying direction of the tubular strand, and
- determine at least one of a temperature within the tubular strand or a temperature on an inside of the tubular strand at a position of the tubular strand based on the the difference between the first and second temperature,
- wherein the second temperature is higher than the first temperature due to thermal conduction from the inside of the tubular strand.
