“…In the study of Szmyrka-Grzebyk [1], RhFe (Rhodiumiron) sensor was calibrated using the cryogenic gas such as hydrogen, neon, oxygen and argon gas. For RhFe calibration liquid nitrogen and liquid helium were used as a heat sink in study of Rickeston [2].…”

The selection of the temperature sensor in the cryogenic system depends on the temperature range, shape and accuracy. The accuracy of the temperature sensor is essential to improve the reliability of experiment. We have developed the variable temperature cryostat using a two-stage cryocooler. In order to reduce heat load, thermal shield is installed at the first stage with MLI (Multiple layer insulation). We have also developed the sensor holder calibrating more than twenty sensors at the same time for saving time and money. The system can calibrate sensor at variable temperature by controlling electric heater. In this paper, we present design and fabrication of variable temperature cryostat and representative result of Cernox sensor calibration.

The argon triple point (T 90 = 83.8058 K) is a fixed point of the International Temperature Scale of Preston-Thomas (Metrologia 27:3, 1990 Springer, New York, 2013). The Institute of Low Temperature and Structure Research has in its disposal a few argon cells of various constructions used for calibration of capsule-type standard platinum resistance thermometers (CSPRT) that were produced within 40 years. These cells differ in terms of mechanical design and thermal properties, as well as source of gas filling the cell. This paper presents data on differences between temperature values obtained during the realization of the triple point of argon in these cells. For determination of the temperature, a heat-pulse method was applied (Pavese and Beciet in Modern gas-based temperature and pressure measurement, Springer, New York, 2013). The comparisons were performed using three CSPRTs. The temperatures difference was determined in relation to a reference function W (T ) = R(T 90 )/R(271.16K) in order to avoid an impact of CSPRT resistance drift between measurements in the argon cells. Melting curves and uncertainty budgets of the measurements are given in the paper. A construction of measuring apparatus is also presented in this paper.

“…Several series of calibrations were performed just after the exposition of two thermometers to different atmospheric factors such as high humidity, high and low temperatures, and rapid temperature changes from −30 to −10 C typical for so-called anticyclonal conditions. Most of the measurements were carried out at the INTiBS, which has at its disposal appropriate measuring equipment for the thermometers' investigation and calibration (Szmyrka-Grzebyk et al, 2011). For this study, a typical Stevenson Screen was located in the INTiBS's garden to reflect accurately the conditions of use of meteorological sensors.…”

This study presents the results of successive calibrations of sensors for meteorological applications consecutively exposed to particular environmental conditions. The determined sensor characteristics and measurement uncertainties were used to analyze how the environmental factors and the ageing of the sensor (impact of the time) results in the variation of characteristics in terms of the sensors’ stability and the reproducibility of the calibration curves obtained. The study consists of the regular calibrations of two temperature sensors: HMP 155 and Vaisala's HMP 45AC, after having been exposed to thermal shocks and exposure to extreme ranges of humidity. The selected measuring devices represent sensors commonly used in Stevenson Screens, compact solar shields and other meteorological applications. The investigation verifies the following impacts on characteristics’ change and reproducibility: time, high humidity, high and low temperatures, and rapid temperature changes (10 series) from −30 to −10°C typical for anticyclonal conditions. The result of the measurements is presented and discussed. The analysis is completed by fully understanding, evaluating and reporting uncertainties in the results.
