Locate hotspots with multipoint temperature-measuring system

| By Chemical Engineering



The Sitrans TO500 multipoint temperature measuring system (photo) enables complex temperature measurements and detection of the precise position of critical hotspots in a variety of applications, including tubular and tube-bundle reactors. The fiber-optics-based device uses a fiber Bragg grating (FBG) for the measurements. The Sitrans TO500 can evaluate 48 FBGs in each of four channels (a total of 192 measuring points), thus enabling precise determination of temperature changes in the smallest spaces. It is said to be the first device to enable FBG-based measurements in industrial environments, such as harsh plant conditions and at high temperatures. The precise determination of the temperature profile enables users to detect critical operating states quickly and initiate countermeasures, thereby lengthening the service life of plants. — Siemens AG, Nuremberg, Germany
