In principle, gas thermometry consists of using the ideal gas law, Eq. The A gas thermometer allows the determination of pressure p and volume V of mass m of the ideal gas with molecular weight μ converting from thermodynamic state 1 to state 2, with the gas mass m = Vpμ/TR remaining constant in both states. A thermometer as recited in claim 3 wherein said first gas is selected from the group consisting of helium, neon, and hydrogen. Concentrations are relatively low, because helium as a noble gas only occurs as separate atoms, and usually does not react with any other particles. Only the measurement of another physical property being a function of temperature may provide temperature determination. By using different gas thermometers a wide range of temperatures can be measured: Hydrogen -200 o C to +500 o C Nitrogen +500 o C to + 1500 o C Helium -270 o C to + 1500 o C These thermometers can be very accurate, to within 0.005 o C from 0 o C to 100 o C, 0.1 o C around 500 o C … A gas thermometer has a case with a case end section (10) made of metal of good thermal conductivity and a main case section (14) made of material of poor thermal conductivity. A property used to measure temperature is termed a thermometric parameter and must meet the following requirements: be independent of the influence of other factors. For the case that the gas volume is filled with Helium, the CVGT operates as closely as possible to the ideal gas law, with the gas pressure being a highly linear function of the absolute temperature over a range easily exceeding 1′000 K. The normal self-heating coefficient for standard capsule-type resistance thermometers is gas-mediated over most of their designed range of use. of a helium gas thermometer calibrated at three temperatures: – Triple point of neon: 24.5561 K – Triple point of equilibrium hydrogen: 13.8033 K – A temperature between 3.0 K and 5.0 K determined via a 3He or 4He vapor pressure thermometer • Between the triple point of equilibrium hydrogen and the freezing Bundesgesetzblatt Bundesgesetzblatt Teil II 1956 Nr.

We have seen that such an ideal-gas thermometer is itself a creature of theory. At a temperature up to 600°C nitrogen is used as a working gas, while above 600°C argon is used. Between 0.65K and 5.0K, the temperature is defined in terms of the vapor pressure - temperature relations of the isotopes of helium. FIRE-FIGHTING MEASURES construction. As working substances, use is made of propyl alcohol, methaxylol, xylol, mercury, etc. In the range 3 K to the triple point of neon (~ 24.6 K), the ITS-90 is defined in terms of a 3He or 4He constant-volume gas thermometer, CVGT, calibrated at three temperatures. Thermometers can be classified according to the nature of substance which expands. The capillary tube communicates with the bottom side of the membrane and a first pressure measurement element on the membrane generates a signal in … Kelvin, in defining his temperature scale kept the centigrade unit of degree, but found experimentally that the centigrade zero actually corresponded to 273.15 K and that the boiling point of water at one atmosphere pressure is 373.15 K. WMO advises that the best representative value of air temperature is the average taken over a one-minute period, meaning that a number of readings should be made if a thermometer with a very small time constant is used. Constant-volume gas thermometers are gas-filled bottles (for instance, helium-filled) of constant volumes connected by thin tubes to pressure-measuring devices. Volume Thermometer. Application of exact relations requires design of complicated devices inconvenient for practical use. But if the capillary tube is filled with nitrogen gas, then the temperature range can be further increased since nitrogen is an inert gas and the pressure exerted by the gas on the mercury can increase the boiling point of mercury. The main drawbacks of this type of instrument are its inevitable thermal lag and its dimensions which are often inconvenient for application. The accuracy of measurement is worse and is determined by the pressure gauge precision. W. L. Tew and C. W. Meyer . For this, corrections are made for the gas nonideal state, thermal expansion of the bulb and capillary, temperature variation, etc. For temperature below 1 K there is the Provisional Low Temperature Scale of 2000 (PLTS 2000). with a gas thermometer provided a strong basis for a revision of the 1948 scale, and an empirical formula was developed by Clement and co"vorkers [8] from which a p-T table could be conveniently calculated to any desired precision, and which fitted the new data to within 0.002 deg throughout the entire range. Clinical mercury thermometers are graduated from 34 to 42°C with a division of 0.1°C and are maximum thermometers, i.e., the capillary column remains on the level of a maximum rise on heating and falls down when shaken.
