Abstract: A method for testing a measuring device is used to determine a permittivity of a frying fat which permittivity is inter alia dependent on the temperature, while taking into consideration the temperature. The method is characterized in that the permittivity is measured at least two different temperatures and the temperature dependence is determined and is used to make a statement on the ability to function of the measuring device.

Abstract: The invention is a device for gauging the status of a material such as a fat or an oil. The device comprises: a housing; a hollow connecting element; a substrate, attached at the opposite end of the hollow connecting element; a sensor, proximate the substrate, for measuring an electrical property of the material being tested; a protective coating, wherein the protective coating covers the sensor and can be applied using either a thin-film or a thick-film technology; and, an electronic evaluation unit connected via at least one electric line to the sensor; and, is arranged proximate the housing and/or proximate the end of the connecting element that faces the housing.

Abstract: The invention relates to a joint which can be subjected to the temperature influences of an external medium (20) and joins an especially ceramic component (2) to an especially metallic component (1). Said joint consists of a first adhesive joint (14) between the metallic component and the ceramic component, and a second adhesive joint (22), the adhesive (16) of the second joint having a higher elasticity than that (10) of the first adhesive joint (14), and the second joint being arranged in such a way that it prevents direct contact between the first adhesive joint (14) and an external medium (20). The inventive joint can preferably be used, for example, preferably in a sensor module of a measuring appliance which can be introduced into a medium to be analyzed.

Abstract: A measuring device is used to measure the state of oils of fats. Said measuring device comprises a housing, a hollow connecting element which is secured therein and a carrier which is applied to the opposite end of the connecting element, said carrier being used to receive a sensor which can be used to measure an electric property of the product which is to be measured. The sensor is in contact with an evaluation unit by means of at least one electric line which is arranged on a non-conductive carrier, which is arranged in the region of the housing and/or the end of the connecting element which is oriented towards the housing. The measuring device comprises a plurality of carriers which are arranged in a row and which are thermally insulated from each other.

Abstract: A measuring device is used to measure the state of a liquid product which is to be measured, in particular oil or fat. Said measuring device comprises a housing, a hollow connecting element which is secured therein and a carrier which is applied to the opposite end of the connecting element, said carrier being used to receive a sensor which can be used to measure the electric property of a product which is to be measured. The sensor is in contact with the measuring unit by means of at least one electric line, which is arranged in the region of the housing and/or with the end of the connecting element oriented towards the housing. The measuring device comprises means which can be used to minimize the falsifying effect of the water content in the product, which is to be measured, on the measuring result.

Abstract: A protective device for a humidity sensor protects the sensor from aggressive substances in a fluid to be analyzed. The protective device for the humidity sensor comprises a protective cap having openings that are covered with a membrane in such a manner that mass transfer between a measuring medium present in the environment and the interior of the protective cap can only take place through the membrane, said membrane including a plastic material which is highly permeable to water vapor, has high thermal stability and high corrosive resistance.

Abstract: The aim of the invention is to provide a simple and reliable method of measuring the quality of a fluid (2), in particular an oil or fat. This is achieved by a dielectric measurement in conjunction with a temperature measurement, which are carried out in situ by means of a measuring assembly and a sensor assembly (1) used with the latter, whereby the sensor assembly is submerged in the fluid. This permits information concerning the condition of the fluid, in particular concerning the age of the frying oil or fat, to be obtained in a rapid, low-cost manner.
