Viability of resistance thermometers under reactor conditions

The viability of six commercial resistance thermometers is examined under reactor conditions; the sensitive element was P1-2 platinum wire of diameter 50 /mu/m. The resistances R/sub 0/ of the thermometers at 0/degree/C were 46.00/plus or minus/0.02 /OMEGA/while the ratios were R/sub 100//R/sub 0/.1...

Zusammenfassung:The viability of six commercial resistance thermometers is examined under reactor conditions; the sensitive element was P1-2 platinum wire of diameter 50 /mu/m. The resistances R/sub 0/ of the thermometers at 0/degree/C were 46.00/plus or minus/0.02 /OMEGA/while the ratios were R/sub 100//R/sub 0/.1.391/plus or minus/0.0007. The design and manufacturing technology have been described. The thermometers were irradiated in a VVR-M reactor. The thermometers were calibrated before and after irradiation outside the reactor by the reference-point method at temperatures of l00, 231.8, and 327.2/degree/C. 7 refs.
