Verkin Institute for Low Temperature Physics and Engineering of the National Academy of Sciences of Ukraine popup.description2 The purpose of the work is to determine the functions of the statistical distribution of parameters of temperature sensors ТП 198-00, ТП 198-01, ТП 198-05 and ТП 227-03 near the boiling temperature of liquid hydrogen. The parameters of temperature sensors TP 198-00, TP 198-01, TP 198-05 and TP 227-03 in the temperature range 12.5-25 K were investigated by means of direct resistance measurements. An original measurement technique was developed, which ensures the temperature stability of the cell with thermometers in within 0.001 K and a relative error of resistance measurements of no more than 0.1% in the entire temperature range. Using the gamma distribution, interpolation polynomials of resistance dependence on temperature were constructed. The obtained results will be used to ensure the stable and reliable operation of temperature sensors in the fuel systems of rocket carriers operating on liquefied hydrogen.  Product Description popup.authors popup.nrat_date 2023-02-07 Close
