S type thermocouple

S ( Platinum rhodium) Thermocouple series of precious metals thermocouple. I wire diameter of the nation is 0. 5 mm, allowable deviation - 0. The positive (015 mm, RP) In the name of the chemical composition of platinum rhodium, contain the rhodium is 13%, platinum-based is 87%, the cathode ( RN） For the pure platinum, long-term * high temperature of 1300 ℃, short-term * high temperature of 1600 ℃.

S ( Platinum rhodium thermocouple) Series in the series of thermocouple with high accuracy *, * good stability, test your area wide, long service life, etc. Its physical and chemical performance is good, the thermoelectric potential stability and oxidation resistance at high temperature is good, suitable for oxidizing and inert atmosphere.

used for a variety of high temperature circumstance in the process of production is widely used in glass, ceramics, industrial salt bath temperature, etc.

thermocouple installation location to facilitate the construction and maintenance. Beside the oven door should be avoided, or from the heating body too close and strong magnetic field, temperature does not exceed 100 ℃ the junction box

. Note: the installation position t the measured temperature value for the thermal element ( ℃) Should be kept vertical, but there are worthy of the oblique flow rate must be installed. Junction box out of the hole should be down.

with porcelain thermocouple protection tube must avoid thermal shock, to prevent blowout, should choose not to interfere with heated objects when installing mobile place. Porcelain pipe protection measure fluid temperature.

thermocouple should be in accordance with the provisions, wiring, lead to avoid heat source, compensation conductor when wiring the polarity is not against. Always check the status of the protection pipe, immediate measures should be taken to find the oxidation or deformation. To check on a regular basis.
