摘要： A method and apparatus are disclosed for the analysis of a fluid to determine the remaining useful life of the fluid and whether the fluid has become contaminated. The method can be performed either on-line or off-line, however, the on-line method is preferred. In the method, a sample of the fluid is contacted by a single electrode which is connected to the ground potential by means of the equipment in which the fluid is used. A current is applied to the sample through the electrode and the conductivity of the sample is measured. The conductivity measurement can then compared to known values for the fluid to determine the remaining useful life of the fluid and whether the fluid has become contaminated.

摘要： A method for the analysis of peroxide in hydrocarbon fuels such as jet fuels, diesel fuel, kerosene and gasoline is disclosed which can be performed both at remote locations as well as in a laboratory setting. A sample of the fuel to be tested is mixed with a solution containing a water-soluble salt and aqueous iodide solution to reduce the peroxide and produce free iodine. The sample is then subjected to a single sweep voltammetric analysis to measure the current through the sample as a function of the potential applied. The resulting peak of current on a current-potential plot can then be used to determine the amount of peroxide in solution.

摘要： A system for measuring light absorption levels includes a light source providing a light beam and a container for a liquid. The container includes an opening to provide access to the liquid. A prism is disposed over the opening and is operable to direct at least a first portion of the light beam toward the opening to the liquid such that the at least a portion of the first portion of the light beam is reflected back from the liquid forming an attenuated beam. A detector is operable to measure at least one of a portion of the attenuated beam and a second portion of the light beam. The detector is operable to produce at least one of a liquid measurement signal and a reference signal. A device is operable to compute a ratio of the liquid measurement signal to the reference signal to determine a signal ratio.

摘要： The present invention relates to a method and apparatus which can be used to detect the abnormal operating condition of equipment, such as engines and machinery, the usefulness of the fluid, and the content of wear metals and elemental constituents in the fluid. The method comprises the steps of bringing at least two electrodes into contact with a sample of a fluid to be analyzed; applying a square voltage wave form to the electrodes at a predetermined scan range and scan rate to cause a current to flow between the electrodes; monitoring the current at the electrodes to determine a current output signal; using the current output signal to measure the conductivity of the fluid; and analyzing the sample to determine a content of wear metals and elemental constituents in the sample.

摘要： A system for measuring light absorption levels for a liquid for use in a printing system includes a light source adapted to provide a divergent beam of light, a liquid container with a hole that acts as a focusing lens, and a prism disposed over the hole to split the divergent beam of light into a reference beam and a measurement beam. The systems include a measurement detector to measure the intensity of the focused beam to produce a liquid measurement signal. A reference detector measures the intensity of the reference beam for compensating the effects of temperature and light source variations on the system signals. A device calculates signal ratios and stores the ratios so that the signal ratios of subsequent colored liquids can be converted into colorant concentrations from a look-up table or through calculations using a signal ratio/colorant concentration.
