20130200883 | MAGNETIC FIELD SENSOR - A magnetic field sensor for a position transducer having processing and control electronics for outputtomg signals of the magnetic field sensor and a permanent magnet exciter array has at least three Hall elements for registering the magnetic field direction of the permanent magnet array. The Hall elements are formed and arranged on a semiconductor IC and spaced in such a manner that their active surfaces lie in a common plane parallel to the surface of the semiconductor IC. A single deflecting body made of ferromagnetic material is is produced and installed as an independent component separate from the semiconductor IC, and the mutual distances of the Hall elements on the surface of the semiconductor IC comprise a multiple of the maximum dimensional extent of the Hall elements. | 08-08-2013 |
20130317761 | METHOD AND APPARATUS FOR DETERMINING THE MASS OF A FLUID FLOWING THROUGH A FLOW RATE METER IN A CONSUMPTION TIME INTERVAL - The mass of a fluid flowing through a flow rate meter at a temperature which fluctuates in a given temperature range is determined by driving an exciter magnet system through the fluid with an exact correlation between the fluid volume flowing there through and the movement path covered by the exciter magnet system, producing a measurement voltage pulse after each passage through a movement path corresponding to a unit volume of the fluid by means of a Wiegand wire and a coil surrounding same, at each measurement time charging a first energy storage means by electric energy contained in each measurement voltage pulse, and using same as operating energy for measurement of the instantaneous temperature of the fluid, producing a temperature value as an integral multiple of the smallest temperature measurement unit to be resolved and an integral count value including said temperature value, and adding same to a sum contained in a non-volatile storage means from the precedingly ascertained count values for forming an ongoing sum in the non-volatile storage means and passing same to a processor which can be supplied with external energy and which calculates therefrom the temperature-corrected delivery volume of the fluid. | 11-28-2013 |
