摘要： The invention relates to a sensor (1) for measuring density profile using gamma rays (5), which is particularly suitable for measuring the level in oil separator tanks. The known measuring principle involves conducting locally resolved measurement of a density-dependent gamma ray transmission of a medium (6a, 6b, 6c) by a vertical linear array (13) of photomultipliers( 7) and using said measurement to determine the location of an oil/water (6c) boundary layer. According to the invention, the gamma ray density sensor (1) is equipped with PIN photodiodes (10) instead of photomultipliers (7). Means for passive cooling for said photodiodes (10) are also provided. This considerably simplifies the structure, operation and maintenance of the sensor and improves local resolution and service life of the sensor (1). Passive cooling can be easily realized by building a thermal bridge (12) between the warm photodiodes (10) and the cool ambient medium or the cool wall (14) of the separator tank. Usability of the sensor (1) under difficult operating conditions and in non-easily accessible locations is generally improved.

摘要： Method for correcting offset drift effects of a thermal measuring device (10) which comprises at least one temperature sensor (15a, 15b), arranged at a defined distance adjacent to a heating device (12) for a fluid to be measured, for the purpose of measuring at least one measurement variable which describes the temperature and/or the temperature profile during operation of the heating device (12), wherein a reference measured value (35) is measured at a reference time in a first measurement of the measurement variable when the heating device (12) is switched off, wherein at at least one later time in a second measurement of the measurement variable when the heating device (12) is switched off a drift measured value (36) is measured, wherein a drift correction is carried out during the measurement using the heating device (12), on the basis of a difference between the drift measured value (36) and the reference measured value (35).
