Stationary stand for the taking up of sensors for thermal analysis of molten metals in foundries and steel works. The stand with the different contact pieces allows a fast contacting and fixing of cups, which are used for thermal analysis. The stand with the integrated active converter module forms the interface between the disposable sensors and the measuring software. All components have been designed for the harsh conditions in liquid metal plants. The data transmission and communication takes place via a digital protocol, which largely excludes environmental disturbances (induction field). The calibration values of the individual channels are stored with their identification and valence directly in the stand and measuring channel-related so as to enable a problem-free external calibration as well as a very fast exchange in case of damage.
