1. Non contact thermometry best done with INFRATHERM pyrometers ISR 12 LO GS Mikron Group Digital 2 color pyrometer with fibre optic for non contact temperature measurement of a cast iron puring stream Automatic recording of the pouring temperature Documentation of the temperature of each single pouring process Replacement or reduction of immersion lance measurements with expandable thermocouples Minimum system maintenance required The pyrometers ISR 12 LO GS is a special foundry system for the meas urement of the pouring stream in foundries This system is useful in automatic or semi automatic pouring machines and displays the tempera ture after each single pouring process A ratio pyrometer is required for this application because e molten metal has a very low and fluctuating emissivity e the position of the pouring stream is moving so that the measuring spot of the pyrometer is only par tially filled Accurate measurement of pouring stream The pyrometer has a special pouring stream mode which calculates one average temperature value for each single casting process Temperature values in the beginning and the end of the casting process can be elimi nated which can affect the correct measurement The shape of the spot size of the optics is a line which guar antees that even a moving pouring stream is always within the spot The pyrometers are equipped with a lens contamination mo2. 01 s 0 05 s 0 25 s 1 s 3 s 10 s Built in single or double storage Clearing with adjusted time tear OFF 0 01 s 0 05 s 0 25 s 1 s 5 s 25 s extern via interface or automatically with the next measuring object hold function to freeze the actual displayed pouring stream temperature max 0 15 A only active with automatic clear mode or tc 0 5 s 0 4 of reading in C 1 C lt 1500 C 0 6 of reading in C 1 C gt 1500 C 0 2 of reading in C 1 C 4 function keys switch for serial interface push button for test current IP 65 DIN 40 050 Converter housing 0 60 C Optical head up to 250 C 20 70 C 2 2 kg Laser targeting light Laser class 2 max laser power level lt 1 mW 655 nm measurement is stopped while laser targeting light is switched on According to EU directives about electromagnetic immunity Converter with display RF eh a a a 2 different optical heads are available They have a special spot size in shape of a line which guarantees that even a moving pour ing stream can always be captured The optical heads differ in its spot size depending on the measuring distance The correct se lection depends on the size of the pouring stream if the pouring stream is moving and the required distance to the stream The optical head has to be adjusted to required measuring dis tance to reach the sp
