    双色红外测温仪的应用

    双色红外测温仪的应用 凡被测温度较高,发射率难于确定,目标太小不能充满视场,测量线路上存在衰减辐射能量物质的情况,都可以用双色红外测温仪解决精确测温的问题,而单色测温仪较难解决上述问题。双色红外测温仪应用领域很广,特别是在钢铁工业、金属热处理、金属加工和铸造等方面。在下述条件下,双色红外测温仪是首选方案。(1) 由于环境中存在的灰尘、烟雾和颗粒造成的能量的衰减;(2) 观测窗和仪器的镜头不清洁;(3) 仪器现场局部受阻或遮蔽;(4) 目标细小,不能充满仪器视场;(5) 目标处于运动或振动中;(6) 测量通道弯曲、狭小、受阻;(7) 金属液体的测量; 例如:钢水、铁水、铜水、铝水、钢处理、金属丝处理、灯丝生产、玻璃工业、感应焊接、金属热处理、铸造、炉和窖、感应加热、管道退火等。
