First-Class Standard Platinum And Rhodium 10-Platinum Thermocouple

Oxidation Resistant Platinum Rhodium 10 Platinum Thermocouple

Part1 Overview

The first and second grade standard platinum-iridium 10-platinum thermocouples which have high accuracy good physical and chemical properties, good oxidation resistance at high temperatures, good stability and reproducibility of thermoelectromotive force. Therefore, it is used as a standard measuring instrument in (419.527~1084.62) °C , it is also used to temperature magnitude transmit and precision temperature measure in the temperature range.

Part2 Technical parameters

Parameter index First grade platinum-iridium 10-platinum thermocouples Second grade platinum-iridium 10-platinum thermocouples
Positive and negative The positive is a platinum-rhodium alloy (platinum 90% rhodium 10%), the negative is pure platinum
electrode Two electrodes diameter is 0.5-0.015mm length is no less than 1000mm

Requirements of the thermal electromotive force

Measure junction temperature is at Cu point(1084.62℃)Al point(660.323℃)

Zn point(419.527℃) and reference junction temperature is 0℃

E(tCu)=10.575±0.015mV

E(tAl)=5.860+0.37 [E(tCu)－10.575]±0.005mV

E(tZn)=3.447+0.18 [E(tCu)－10.575]±0.005mV
Stability of Thermo-electromotive force 3μV 5μV
Annual change Thermo-electromotive force at Cu point(1084.62℃) ≦5μV ≦10μV
Working Temperature Range 300~1100℃
Insulating sleeve

Double hole porcelain tube or corundum tube

Outer diameter(3~4)mm, hole diameter(0.8~1.0)mm, length(500~550)mm

Part3 Precautions when use

1. The insulation tube cannot be used at high temperature roasting. The original insulation tube is used after strict cleaning and high temperature roasting.

2. The insulation tube ignores positive and negative, which will cause the platinum pole to be contaminated and the thermoelectric potential value to decrease.

3. Randomly the standard thermocouple insulation tube with cheap wire will contaminate the standard thermocouple, and the protective metal tube must be used for the verification of the base metal thermocouple.

4. The standard thermocouple cannot be suddenly placed in the temperature-regulating furnace, nor be taken out from the temperature-regulating furnace. The sudden-heat and cold will affect the thermoelectric performance

5.Under normal circumstances, the verification furnace for the precious metal thermocouple and the base metal thermocouple should be strictly distinguished; if it is impossible, the clean ceramic tube or corundum tube(diameter about 15mm) should be inserted to the furnace tube for protecting precious metal Thermocouples and standard thermocouples from base metal thermocouple pollution.
