Abstract: A system and method (1) for acquiring, compiling and storing measured values in a temperature and/or pressure and/or moisture-dependent process comprises at least one sensor (4, 6) for acquiring measured values. The device (1) contains means (3) for storing the measured values. The sensor (4, 6) and the means (3) are designed to be positioned inside a closed process chamber (2). The device (1) further comprises means (11) for the wireless transmission of the stored measured values at preset or settable time intervals to a receiver unit (10) disposed outside the closed process chamber (2). In a process for monitoring a temperature and/or pressure and/or moisture-dependent process, an acquisition of measured values is accomplished by means of at least one sensor (4, 6) located inside a closed process chamber (2).

Abstract: Disclosed is a method for measuring at least one state characteristic of oil or fat in a device that uses oil or fat and is provided with a filtering apparatus (1; 101) comprising a filter housing (2) and at least one filter element (7) which is inserted thereinto. According to said method, at least one sensor (35, 36; 135; 235) of a measuring device (30; 130; 230) is introduced into a measurement space (8; 208) located in the oil or fat circuit in order to measure at least one state characteristic of the oil or fat, and the measured values thereof are evaluated using measuring electronics (32; 132) that are connected to the at least one sensor (35, 36; 135; 235). The inventive method is characterized in that a microfilter element, ultrafilter element, or nanofilter element (7) is used as a filter element. Also disclosed are a corresponding filtering apparatus (1) and a correspondingly configured measuring device (130).

Abstract: The present invention relates to a process and device for the monitoring of fats and oils in the preparation of food, which provide for the exchange of oil or fat in a timely manner, before they have become harmful for human consumption. The proposed process for measurement distinguishes itself by the fact that the measurement is already taking place during the temperature adaptation of the sensor, whereby a measurement can take place which is particularly fast and thus suitable for use in practice. Along with this, the device is formed in such a manner that disturbances of the measurement can be largely eliminated.

Abstract: A measuring device (1) is suggested for determining the quality of oils or fats, in particular for being used in conjunction with the preparation of foods, which device has a simple construction and is easy to handle. It comprises a measuring head (12) on which a sensor (5) is attached which measures the electric constant of the oil. The measured value is further processed in electronics of the device and a statement about the state of the quality of the oil is made. The measuring head (12) is attached via an attachment (11) to a housing (10) containing the measuring electronics, the energy supply and a display (2) for the determined state of the oil or fat.

Abstract: A measuring device is proposed to measure the gas pressure of an atmosphere, whereby the measuring device is provided with a sensor to measure the pressure located in the interior of a housing which encloses the sensor. In addition a unit to control the measuring device and to evaluate the signals as well as a supply unit are installed in this housing. The housing itself is sealed off against the surrounding atmosphere and is provided with contacts on the housing for the exchange of data between the measuring device and a unit for the evaluation of measured values connected to it. The contacts are provided at the same time to ensure that the unit for the evaluation of the signal of the pressure sensor can be supplied with control signals from outside the housing.
