A/D converter used the ADS1232, both to ensure the accuracy and guarantee the speed, in line with rapid temperature measurement requirements;rapid temperature even when the fault may occur, which through the algorithm processing, according to breaking even before the thermometer measure the temperature calculated or to determine the temperature failed;can be equipped with S, B, R, WRe3-25 thermocouple number of four divisions, to achieve different temperature ranges of temperature;with high brightness 5LED large font display, easy operation and reading of the reading operator. This thermometer to overcome the non-contact measurement accuracy is not high disadvantage and reduces the cost for the realization of molten steel, iron; liquid fast, accurate temperature measurement provides an effective and practical method.
