Abstract: A temperature measuring device for determining a temperature of a medium via a temperature of a measuring point on a surface surrounding the medium includes: at least one measuring sensor; at least one reference sensor; and a measurement value processing means, which is connected via a first supply line to the at least one measuring sensor and via a second supply line to the at least one reference sensor. The first and second supply lines each are mineral-insulated sheathed lines with an outer sheath of metal, the outer sheath enclosing at least two inner conductors which are insulated from the outer sheath with highly compressed metal oxide powder. The at least one measuring sensor is connected to the at least two inner conductors of the first supply line and the at least one reference sensor is connected to the at least two inner conductors of the second supply line.

Abstract: A system and method includes at least one temperature sensor, a processing unit, and an output unit. The temperature sensor acquires a temperature measurement at a first location of an operational device, which first location is in thermal contact with a second location of the operational device. The processing unit selects a simulated temperature distribution of the first location of a simulated device from a plurality of simulated temperature distributions of the first location and compares the temperature measurement with simulated temperature distributions of the first location, and determines whether a hot spot exists or is developing at the second location. The determination comprises utilization of a correlation between the simulated temperature distribution of the first location and the second location for the selected simulated temperature distribution of the first location of the simulated device.

Abstract: A pressure sensor for a pipe includes: a flexible strip; at least one strain sensing element; and a tensioning device. A first end of the flexible strip passes through a second end of the flexible strip. Between the first end of the flexible strip and the second end of the flexible strip, the flexible strip includes the at least one strain sensing element. The pressure sensor is attachable to the pipe. The first end of the flexible strip extends through or past the second end of the flexible strip. The tensioning device tensions the pressure sensor around the pipe.

Abstract: A temperature measuring device for determining a medium temperature by a temperature of a measuring point on a surface enclosing the medium includes: at least one measuring sensor; at least one reference sensor; and a measured value processing device which is connected via a cable to the at least one measuring sensor and via a cable to the at least one reference sensor. The at least one measuring sensor and the at least one reference sensor are arranged along a main thermal connection path between the surface enclosing the medium and surroundings. The at least one measuring sensor is arranged close to the measuring point. A thermal resistance between a relevant measuring sensor and the at least one reference sensor is smaller than a thermal resistance between a relevant reference sensor and the surroundings.

Abstract: A system and method includes an infrared camera; a processing unit; and an output unit. The infrared camera is configured to acquire a plurality of infrared images of the device, wherein the plurality of infrared images comprises a first infrared image and a second infrared image acquired a time period after the first infrared image. The processing unit is configured to determine a pixel in the first infrared image with a hottest temperature and determine a pixel in the second infrared image with a hottest temperature. The processing unit is configured to determine a first number of pixels in the first infrared image that have a temperature within a threshold temperature of the hottest temperature of the first infrared image and determine a second number of pixels in the second infrared image that have a temperature within the threshold temperature of the hottest temperature of the second infrared image.
