摘要： The invention relates to a method and apparatus for measurement of total water content in a liquid. According to the method, the relative water content (aw) of the liquid is measured in a first measurement step at a first temperature (T1). According to the invention, the temperature of the liquid under measurement is altered from the first temperature (T1) and the relative water content is measured in a second measurement step at the second, altered temperature (T2), whereby, based on these at least two measurement values (aw(1)T1, aw(2)T2), the total water content is determined from the temperature dependence of water dissolution into the liquid under measurement.

摘要： The invention relates to an indirect measurement method of dewpoint or gas concentration and an apparatus suited for prediction of icing. The method is based on measuring the relative concentration of the gas directly and simultaneously measuring the temperature of the element (3) measuring the relative concentration of the gas. According to the invention, the temperature of the relative value measuring element (3) is shifted so as to bring the operation of the measuring element to a measurement range of maximally high sensitivity.

摘要： Detector and method for detecting the presence of a liquid, such as water dew or of ice, or for detecting a change of phase in liquid, based on a change in an electrical resistance. The detector comprises a substrate onto whose face one or several resistor patterns are applied. For detecting the presence of a liquid or ice or equivalent by a change in the detector resistance, a low-mass detector resistor pattern is applied onto a substrate out of such a metal or equivalent as has a considerable dependence on temperature. On the substrate, there are contact patterns that feed a short pulse of electric current to heat the detector resistor as a short pulse, the presence of a liquid or ice and or a change of phase being detected by the change in resistance taking place during the short pulse. The thickness of the metal film in the resistor pattern (15) of the detector resistor (R.sub.det) is, as a rule, chosen as s

摘要： This invention concerns a method for trimming a planar capacitor. According to the method, a laser emission is focused to an electrode of a capacitor formed on a substrate transparent to laser emission and including of an upper electrode, an insulation layer, and a lower electrode, in order to achieve a passivation effect on the electrode. The laser emission is focused according to the invention locally onto the lower electrode through the substrate in order to achieve a heating effect on the lower electrode, thereby oxidizing the electrode material so that the lower electrode is locally converted into an electrically nonconductive state while being protected by the substrate and the insulation layer. The trimming method in accordance with the invention is accurate and offers a stable capacitance value.

摘要： A method and system relating to an improvement in measuring accuracy of a gas concentration sensor, the method comprising the steps of measuring a parameter of the sensor, the parameter being a resistance or a capacitance, that is sensitive to the gas or its concentration being measured, and simultaneously changing the temperature of the sensor in a cyclic manner. The parameter of the sensor being measured is measured more than two times or continuously during each heating cycle. The measured parameter value is filtered to obtain a signal component associated with the fundamental frequency of the heating cycle for use at a later step, and the thus filtered signal component is used in the correction and/or calibration of actual output signal of the sensor.
