· SIGMA超高溫的定義:在氧化氣氛條件下，1800℃以上的溫場(chǎng)稱為超高溫溫場(chǎng)，能夠長期接觸式測(cè)定1800℃以上的溫場(chǎng)的溫度傳感器稱為超高溫傳感器，能夠在1800℃以上長期使用的發(fā)熱元件稱為超高溫發(fā)熱元件，能夠在1800℃以上長期使用的的箱式電阻爐稱為超高溫箱式電阻爐。
· SIGMA Ultra-high temperature definition: in an oxidizing atmosphere conditions, above 1800 ℃ ultra-high temperature field called field gentle. Long-term contact measuring temperatures above 1800 ℃ temperature field sensor is called ultra-high temperature sensor. Long-term use of heating element above 1800 ℃ is called ultra-high temperature heating element. It is possible above 1800 ℃ long-term use of the box-type resistance furnace known as ultra-high temperature box resistance furnace.
