摘要： A multipurpose monitoring system provides instantaneous, simultaneous and continuous acquisition and storage of changes in concentrations of oxygen and inorganic ions such as Ca2null, Knull, Hnull, TPPnull, the changes in the intensity of light scattered by a sample and changes in the fluorescence of the sample. The system provides for simultaneous operation of three (or more) ion-selective electrodes using a single reference electrode having a high polarization limit. The electrodes are laterally integrated into a measuring chamber having low volume. The design of the chamber and holders for the electrodes provide for a hermetically sealed attachment of electrodes within the chamber. In addition, the system integrates an electrically insulated oxygen sensor, allowing simultaneous measurements of the concentration ionic composition and dissolved oxygen in aqueous solutions.

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： A gas detection sensor which combines the advantages of constant-temperature operation and PWM control for catalytic-bead, combustible-gas detectors. The active and reference elements of the gas detector are arranged in a modified bridge circuit which allows power to be supplied, using pulse-width modulation, separately to the active and reference elements. An advantage is that constant temperature can be maintained on the elements by using a relatively inexpensive digital processor to monitor the resistances of the elements to control the pulse-width modulator, and to translate the decrease in power needed to maintain constant temperature on the catalytic element into an output proportional to the concentration of combustible gas in air. Thus, a system embodying the foregoing periodically measures the resistance of one or more sensor elements (Rref and Rsense) and controls the electrical bias applied to the elements, using PWM, thereby maintaining nearly constant temperatures in the sensor elements. Changes in gas concentrations are reflected in changing electrical bias. Another advantage is that the gas detection sensor enables dual operating modes of catalytic-bead detectors. One sensor can alternately measure low concentrations of combustible gases up to the lower explosive limit (LEL) or measure high concentrations, up to 100% by volume.

摘要： A sample holder for differential thermal analysis has a substrate with a planar surface provided with a sample position for a sample material and a reference position for reference material. The substrate allows heat flow between a heat source thermally coupled to the sample holder and the sample and reference positions. A first thermoelement arrangement in the area of the sample and reference positions is provided for supplying a thermoelectric signal corresponding to a differential between the temperatures at the sample and reference positions. First connectors are formed on the substrate for tapping the thermoelectric signal corresponding to the temperature differential. A second thermoelement arrangement provides a thermoelectric signal corresponding to an absolute temperature of the sample and reference positions. Second connectors are provided on the substrate for tapping the thermoelectric signal corresponding to the absolute temperature.

摘要： A method that utilizes a dispersion-shifted fiber having compound compositions with different temperature coefficients in core to simultaneously measure the distributed strain and temperature based on Brillouin frequency shift is disclosed. The present method includes the steps of obtaining mean two peak frequencies in a multi-peak Brillouin spectrum of the dispersion-shifted fiber, determining a temperature change according to the formula of a Brillouin frequency shift of the peak relating to strain and temperature conditions of the fiber, and determining a strain change through the formula. In a 3682-m sensing length of Large-Effective-Area NZ-DS fiber, a temperature resolution of 5null C., a strain resolution of 60 nullnull and a spatial resolution of 2 m are achieve simultaneously.
