Abstract
Local liquid sample heating is used in multiparametric sensors of liquid type classification and in sensors of liquid flow. In such applications, the heating of the liquid is done by micro-heaters, with the liquid separated from the micro-heater. The presented paper concentrates on the physical conditions of liquid sample heating used in capillary sensors. In such devices the repeatable transfer of heat is required. The basic measurements include time of liquid to vapor phase transitions and local transfer of heat. In the work were used experimental and simulation techniques. The obtained results show that in the capillary sensor repeatable local heat transfer conditions can be easier achieved than repeatable time of liquid to vapor phase transitions. In the analyzed case, the local heating depends mostly on the capillary to micro-heater distance. The liquid to vapor transition times, beside of the liquid type, depend on the powers used for micro-heater heating and on capillary cross-section parameters, such as the inner and outer diameter values. By increasing the power to the micro-heater the transition time variability is reduced.
