Claim Text:
1. An NMR measuring system for analysis of a solid and/or liquid sample substance disposed within an NMR sample vial, the NMR measuring system comprising: an NMR spectrometer, said NMR spectrometer having structure defining a measurement space, wherein said structure defining said measurement space is adapted to accept the NMR sample vial and to hold the sample vial at a measuring position, said NMR spectrometer also having NMR coils surrounding said measuring position and temperature-control fluid components structured to direct a temperature-control fluid to flow around the sample vial at said measuring position, said NMR spectrometer further comprising a temperature control device, wherein said temperature control device comprises: a controlled heater, said controlled heater communicating with the temperature-control fluid in a supply flow to said measuring position; at least one temperature sensor having a temperature-sensitive measuring head positioned in a spatial vicinity of said measuring position and at least partially projecting into said measurement space, wherein said temperature sensor has supply wires to said measuring head which are disposed in a space that is separate from said measurement space; and a sensor tube, said sensor tube surrounding said temperature sensor and said supply wires at a radial distance, wherein said sensor tube communicates with said measurement space via a sensor flow inlet and is structured to direct a partial flow of the temperature-control fluid to flow as a temperature-control flow out of said measurement space into a free space between said temperature sensor and an inner wall of said sensor tube to pass along said supply wires and flow out of said sensor tube via a sensor flow outlet at an end of said sensor tube opposite said sensor flow inlet or through side openings in a wall of said sensor tube, said sensor tube being cylindrical and having a circular, oval, polygonal or rectangular cross-section, wherein a clearance cross-section of said sensor tube has different magnitudes at different axial positions of said sensor tube.
