ISQ 5-LO测温仪是一款数字式、高精度、双色测温仪,配有光纤测头,用于非接触式温度测量。

这款测温仪根据双色原理(比率原理)进行测温,这一原理是由两条相邻的波长用于温度的传输。相对于单色的测温仪,比率测温仪有以下优点:测量结果在很宽的温度范围内不受测量物体本身辐射率的影响;测量结果不受测量视域内灰尘及其他污染物的影响,也不会受到被污染视窗的影响,测量物体可小于光斑尺寸。

此外,该测温仪可切换至单色模式,与传统的测温仪一样进行测温。该仪器配备了一根光纤(最长可达30米),在无制冷的条件下耐温可达250°C,同时还不会受到电磁干扰的影响。

根据不同的测量距离,有两个不同的测头可供选择,可实现极小的光斑尺寸。响应时间仅需10毫秒,可实现快速加热过程的测量。大部分重要的参数都能直接在该仪器内进行设置,所有仪器的参数可通过便携式设定装置HT 6000或数字式指示器DA 6000-N进行调整。还可通过电脑和标准操作软件InfraWin对参数进行设置。此外,这一软件具有在线温度显示和数据存储的功能。

典型应用:

  • 感应加热
  • 焊接
  • 铸造
  • 锻造
  • 退火
  • 烧结
  • 轧钢厂旋转窑
  • 浇注流
