20100140480 | Radiometric Level or Density Measurement - A level or density of a medium in a tank is radiometrically measured by detecting the light flashes generated by a scintillator with an array of photodiodes. Corresponding voltage pulses are summed up and analyzed with respect to their relevance before they are used for determining the level or the density of the medium. | 06-10-2010 |
20100200756 | OPTICAL LIQUID SENSOR - The inventive optical sensor consists of an LED semiconductor material and elements (herein after the LED components) surrounded by a transparent encapsulant that allows much of the light produced by the LED components to pass while a certain small percentage of the light is internally reflected. The percentage of light internally reflected, depends upon whether at least a front face of the encapsulant is immersed in liquid or in air. The optical liquid sensor also consists of a strategically placed photo sensor that detects the intensity of light that is internally reflected by at least the front face of the encapsulant surrounding the LED. The photo sensor is able to detect the change in intensity of light being internally reflected by at least the front face of the encapsulated LED when the front face, for example, emerges from immersion in a liquid. | 08-12-2010 |
20100230600 | Radiometric measuring device with a two-wire supply - A measuring device with a two-wire supply for radiometric filling level measuring or density measuring of a feed material with a processor which is designed to change from an active mode to a power-saving mode. | 09-16-2010 |
20100252739 | Radiometric Measuring Device - A radiometric for measuring a physical, measured variable of a fill substance located in a container and for outputting a measurement signal, which corresponds to a measured value of the physical, measured variable. The measuring device has available a single line-pair, via which energy supply of the total measuring device occurs, and via which transmission of the measurement signal occurs. The measuring device includes: a radioactive radiator, which, during operation, sends radioactive radiation through the container; a detector having a scintillator and a photomultiplier and serving for detecting, and for converting into an electrical output signal, radiation intensity penetrating through the container dependent on the physical, measured variable to be measured; a measuring device electronics, which serves, on the basis of the electrical output signal of the detector, for producing the measurement signal and for making such available via the line-pair; an energy storer supplied via the line-pair; a controller, which, as a function of energy available via the line-pair and the energy storer, triggers measuring phases, during which the measuring device measures the physical, measured variable, and which places the photomultiplier in operation exclusively during the measuring phases, wherein high voltages required for operating the photomultiplier are produced during the measuring phases by means of a high voltage cascade. | 10-07-2010 |
20110168899 | DETECTOR ASSEMBLIES AND SYSTEMS HAVING MODULAR HOUSING CONFIGURATION - A detector assembly includes an elongate structure and a scintillation detector. The elongate structure defines a detector cavity having an axial dimension extending along a longitudinal axis. The scintillation detector is disposed at least partially within the detector cavity. The detector system can also include a cabinet which can be coupled with an end of the elongate structure, and which can define a cabinet cavity for retaining a junction board, a display screen, a microprocessor unit, and/or other components. The detector assembly can have an explosion-proof rating. A detector system including the detector assembly and a detector unit is also provided, such as for use in applications requiring an explosion-proof rating. | 07-14-2011 |
