它是一种高温抽气热电偶,结构新颖,成本低廉,所用铠装铂铑热电偶长度0.1—0.13米。使用条件易于实现,即喷射介质压力2.5—3kg/cm~2,也可用单相220伏电源作动力,配套供给小型抽气机。冷却水2kg/cm~2。仪器灵敏度极高,因此除能快速测量高温气体温度外,还可以较真实地测出工业炉火焰的温度场。若用抽气机,在测温同时,可附带取出气样,供成分分析之用,具有取样快,气样迅速冷却的优点。 原有高温抽气热电偶的铠装铂铑偶是全长的,取探头多长,偶也多长,φ2mm的偶每米约三千元。现只需长0.1—0.13米,φ1.5mm,价约200多元。这就显著地降低成
It is a high-temperature exhaust thermocouple, novel structure, low cost, the length of armor platinum rhodium thermocouple 0.1-0.13 meters. The use of conditions easy to implement, that is, the injection medium pressure 2.5-3kg / cm ~ 2, can also be used as a single-phase 220V power supply, supporting the supply of small suction machine. Cooling water 2kg / cm ~ 2. High sensitivity of the instrument, so in addition to rapid measurement of high temperature gas temperature, but also can more accurately measure the industrial furnace flame temperature field. If the use of air suction, temperature measurement at the same time, with the removal of gas samples can be used for the composition of the analysis, with a sample quickly, the advantages of rapid cooling of gas samples. The original high-temperature extraction thermocouple armor platinum rhodium even full-length, take the probe how long, even long, φ2mm even about three thousand dollars per meter. Now only 0.1-0.13 meters long, φ1.5mm, priced at about 200 yuan. This is significantly reduced to
