High quality of insulation of the three kinds of precious metal thermocouple temperature measuring line is introduced

Platinum rhodium thermocouple wire S, R and B of the three. The R and S applicable temperature range of 1398 ~ 1482 & deg; C ( 2550 ~ 2700° F) ； B type suitable for temperature up to 1704 & deg; C ( 3100° F) Under the condition of continuous use.

in order to effectively prevent under the condition of high temperature oxidation and corrosion, provide three chang instruments may be applied to three types & quot; Precious metals & quot; The high quality of thermocouple temperature insulation line:

S: platinum ( - ) With platinum rhodium (10% +)

R type: platinum ( - ) With platinum rhodium (13% +)

B: platinum rhodium (6% - ) With platinum rhodium (30% +)

R and S recommended at temperatures up to 1398 & deg; C ( 2550° F) Continuous use or inert atmosphere of oxidation, or in 1482 & deg; C ( 2700° F) Short-term exposure to use of high temperature conditions. Type B is suitable for the temperature as high as 1704 & deg; C ( 3100° F) The oxidation of continuous use or inert atmosphere. When close to the maximum temperature job, it is recommended that the wire diameter of large size.

all three types of thermocouple can be used in vacuum environment short to medium term. When applied in the vacuum environment, type B provides the best stability. Three kinds of models are not suitable for in reducing gas or containing metal or nonmetal steam environment, unless the non-metallic protective casing. Do not insert the thermocouple direct metal protective casing.

temperature measuring wire diameter range 0. 025-0. 812毫米( 0. 001-0. 032' ) 。 If necessary, thermocouple wire can meet or exceed the limit standard error matching suppliers. Special error limit temperature measurement line supply as required, and must be matching order.
