热电偶高温計使用了一定的时间以后,由于它长时間放置在高温中,經常受到有害气体的浸蝕,或是由于保护套管的破裂,使热电偶絲直接和高温火焰相接触,往往会使热电偶氧化和剝蝕,使偶絲变細或断裂,影响温度的測量。在这情形下,就必須把它拆开,将热电偶的“热端”重新焊接起来,以便繼续使用。 Thermocouple pyrometer after a certain period of time, because it is placed in high temperature for a long time, often by the erosion of harmful gases, or because of the protective sleeve rupture, the thermocouple wire and high temperature flame directly contact, often So that the thermocouple oxidation and erosion, make the wire thinner or broken, affecting the temperature measurement. In this case, it must be disassembled, the thermocouple’s “hot end” welded back in order to continue to use.
