| ** | In order to avoid gelling, it is recommended not to exceed a temperature of 200°C for a long time; even for fluids with wider operating ranges |
| (1) | Usable range The “usable range” of a calibration liquid is the temperature range in which it can be used under optimum conditions. The range may be limited by viscosity, flash points, freezing points, boiling points, evaporation rates, tendency to gel (or polymerize), etc. There is no liquid that covers extremely wide temperature ranges. Therefore, you should ideally use a separate calibration liquid for each temperature range. The recommended range is the one in which the viscosity is not optimal, but still reaches values that allow proper use. |
| (2) | Use of a fume hood The use of an exhaust hood when using temperature calibration baths prevents users from inhaling vapors from calibration liquids. It is best to use extraction devices near the access opening to the calibration bath. Vapors can otherwise settle on the mucous membranes of the eyes or on the skin, causing discomfort. Silicone oils can form benzene and formaldehyde when they decompose at high temperatures. The table shows the temperature above which an extractor hood should be used. |
| (3) | Flash point The table shows the temperature value at which the presence of an open flame can ignite vapours combustion. |
| (4) | Viscosity Viscosity is a measure of the flow resistance of a liquid. Viscosity increases with decreasing temperature. Kinetic viscosity is the ratio of absolute viscosity to density. This is measured in stokes and centistokes (cSt). 1 cSt = 1 stoke divided by 100. The higher the cSt, the more viscous or dense the liquid. Excessively viscous liquids place a strain on the stirring and pumping mechanisms of the calibration bath and do not transfer heat sufficiently. The table shows the temperature value below which the performance of the temperature calibration bath is no longer optimal. The equivalent value of water at 20°C is 1.1 cst. |
| (5) | Freezing point Silicone oils also change their state below a certain temperature by solidifying. The table shows the value at which the calibration fluid changes its state and solidifies. |
Other physical and chemical properties
Specific heat
The specific heat is the amount of heat required to raise or lower the temperature by 1 °C per kg. The specific heat, called CP, is expressed in Kcal/Kg °C. The energy required to heat or cool the calibration liquids depends on the amount of liquid contained in the calibrator in kg and its specific heat. A high specific heat value requires more energy to change the temperature, but offers greater temperature stability. The average CP of silicone fluids is 35 Kcal/Kg °C. The CP of water at 20 °C is equal to 1.
Thermal conductivity
Thermal conductivity is the ability of the liquid to transfer heat from one molecule to another. The better the heat transfer, the faster the liquid heats or cools. Better thermal conductivity improves the temperature uniformity in the reservoir of the calibration bath.
Expansion
All liquids have a coefficient of thermal expansion. This indicates how much the volume of a liquid changes (expands or contracts) when the temperature changes. Liquid expansion has an important impact on the safety, cleanliness and maintenance of temperature calibration baths. If calibrators are filled with too much liquid at a low temperature and then heated without regard to the increase in volume, they can overflow.
If too little liquid is filled in the reservoir, below the level of the heating elements, the temperature rise of the non-immersed part of the heating elements could ignite the liquid.
Gelation (polymerization)
The gelling temperature is the temperature at which silicone fluids oxidize, gel and turn into a viscous slurry. The main cause of this phenomenon is oxidation. Although silicone fluids can be used safely up to their flash point, the susceptibility to polymerization increases when used above their oxidation point. To prevent polymerization, it is advisable to keep the operating time above the oxidation point of the silicone oil used as short as possible in order to keep contaminants (salts, other oils and oxidizing agents) away. The calibration fluid must be replaced if it becomes dark, viscous or temperature unstable. It is important to limit the application time at high temperatures to prevent the oil from degrading and to extend its service life.
