    摘要: A device for determining the temperature of a medium includes a temperature sensor with a resistance element placed in electrical contact using first and second connection lines, wherein the first connection line is divided into a first section and a second section. The first section faces the sensor element and is composed of a first material, and the second section faces away from the sensor element and is composed of a second material which differs from the first material. The second connection line is composed of the second material. The first section of the first connection line and at least one part of the second connection line form a first difference temperature sensor in the form of a thermocouple. The first and second connection lines are attached to the resistance element so that the first difference temperature sensor detects a temperature gradient at the location of the temperature sensor.

    摘要: The present disclosure relates to a device for determining and/or monitoring temperature of a liquid, comprising a temperature sensor, a reference element for in-situ calibration and/or validation of a temperature sensor and an electronics unit, wherein the reference element is composed at least partially of a material, in the case of which at least one phase transformation occurs at at least a first predetermined phase transformation temperature in a temperature range relevant for calibrating the temperature sensor, in which phase transformation the material remains in the solid phase. According to the present disclosure, the electronics unit is embodied to supply the reference element with a dynamic excitation signal. Furthermore, the present disclosure relates to a method for calibration and/or validation of a temperature sensor based on a device of the invention.

    摘要: The present disclosure relates to an apparatus for determining and/or monitoring temperature of a liquid. The apparatus includes at least one temperature sensor arranged in a sensor head. Furthermore, the present disclosure relates to a method for manufacturing the apparatus. At least one internal volume of the sensor head is at least partially filled with at least one first material and at least one second material. The first material serves for affixing at least one component of the temperature sensor within the sensor head, and the second material serves for heat conduction within the sensor head.

    摘要: The present disclosure relates to a method and apparatus for in-situ calibration and/or validation of a thermometer having a temperature sensor and a reference element composed at least partially of a material that undergoes a phase transformation at a phase transformation temperature, wherein the material remains in the solid phase in the phase transformation, the method including detecting and/or registering a measured value from the temperature sensor; detecting and/or registering a reference variable of the reference element; detecting the occurrence of the phase transformation based on a change of the reference variable; ascertaining a phase transformation time at which the phase transformation occurs; determining a sensor temperature using the temperature sensor at a measurement time that has the shortest time separation from the phase transformation time; and comparing the sensor temperature with the phase transformation temperature and/or determining a difference between the sensor temperature and the phase transformation temperature.

    摘要: Disclosed is a method for checking the setting of predefined security functions of a field device of process and automation technology, wherein the predefined security functions relate to an access to a function of the field device by an unauthorized person. The method includes: identifying a user; starting by the user a query about the actual setting of the security functions predefined at the measuring point; comparing actual setting of the predefined security functions with a target setting of the predefined security functions defined by the stipulated security level; and outputting an electronic report about the matching or deviation of the actual setting from the target setting of the predefined security functions. Depending on the matching or deviation of the actual setting from the target setting of the predefined security functions, different steps are carried out.
