Reasonable choice of thermocouple

Reasonable choice of thermocouple
Generally, the protective sleeve of the thermocouple is selected according to the measurement medium, and the thermocouple model is selected for the temperature measurement temperature. When selecting a suitable thermocouple , it is generally determined according to your process conditions, the connection method is selected according to the pressure level, the appropriate graduation number is selected according to the temperature of the medium, and the protective sleeves of different materials are selected according to the characteristics of the medium. Select explosion-proof and protection level.

      但是真正达到世界品质的还没有,大家的生产工艺基本一样,只是在销售形式方面差异比较大,并没有在专利和自有技术有所突出。 Although there are numerous domestic manufacturers of thermocouples , they have not yet achieved the world's quality . Everyone's production process is basically the same , but there are large differences in the form of sales , and they are not prominent in patents and proprietary technologies. 寿命长 There are three key points of thermocouples : ( 1) Long life   精度高 ( 2) High accuracy   精度衰退小。 ( 3) The accuracy degradation is small. 目前国产的平均使用寿命在3个月左右,而且还不能保证安全生产,而日本的山里YAMARI产品可以达到2年以上,并且可以保证精度不变。 For example, the thermocouple used in the blast furnace hot air furnace of the iron and steel industry currently has an average domestic service life of about 3 months , and it cannot guarantee safe production . The Yamari products in Japan can reach more than 2 years, and the accuracy can be guaranteed. 热电偶。 It is understood that the hot air stoves of large domestic steel companies are also using YAMARI thermocouples. 然而日本YAMARI山里并不是焊接,而是激光融溶技术,没有焊接点.这就保证了热电偶使用寿命的更长! In China, the cores of different materials required by national standards are all welded . However, YAMARI in Japan is not welded , but laser melting technology , there are no welding points . This guarantees a longer thermocouple life !
