Embodiment Construction

[0022] figure 1 A frying oil and / or frying fat sensor for determining the quality of frying oil and / or frying fat is shown as a whole with 1 . The frying oil and / or frying fat sensor 1 has a conductor structure 2 on the proximal end 3 of which electronic components 5 are arranged.

[0023] The conductor structure 2 has an inner conductor 6 and an outer conductor 7 between which an electric field can be formed. The inner conductor 6 and the outer conductor 7 are arranged in a measurement space 13 formed by the housing of the conductor structure 2 . Between the inner conductor 6 and the outer conductor 7 a measurement channel 14 is formed for a measurement capacitor whose capacitance is measurable. The inner conductor 6 and the outer conductor 7 are arranged coaxially to each other, wherein the radial distance between the inner conductor 6 and the outer conductor 7 in the measuring channel 14 is constant and / or equal in size over the entire measuring channel 14 .

Abstract

The invention relates to a frying oil and / or frying fat sensor (1) for determining the quality of frying oil and / or frying fat, comprising a conductor structure (2) which is fixedly connected at the proximal end to an electronic component ( 5) Connection, wherein the conductor structure (2) has an inner conductor (6) and an outer conductor (7), which are arranged coaxially to each other and which are fixedly connected to the electronic component at the proximal end , wherein the inner conductor ( 6 ) is movably guided relative to the outer conductor ( 7 ) in the axial direction at at least one free end for compensation of temperature-dependent mechanical stresses.

Description

technical field [0001] The invention relates to a frying oil and / or frying fat sensor for determining the quality of frying oil and / or frying fat, comprising a conductor structure, an electronic component arranged at the proximal end of the conductor structure, wherein the conductor structure has an internal A conductor and an outer conductor are arranged coaxially with each other. Background technique [0002] Such frying oil and / or frying fat sensors for determining the quality of frying oil and / or frying fat are known and are used to regularly check the quality of the oil and / or fat used for frying food. This can be done, for example, by means of capacitive sensors, the measured capacitance of the oil and / or fat changing as a function of its age. [0003] However, the previously known frying oil and / or frying fat sensors of the type mentioned at the outset have the disadvantage that, due to the high operating temperature in the oil and / or fat pool, for example, conductor...
