FAQ
Q:What's the difference between Type R and Type S?
A:Type R has higher Rh content (13% vs 10% for Type S), better high-temp stability, but slightly higher cost.
Q:Why is Type R sensitive to contamination?
A:Precious metal materials are prone to impurity (e.g., S, Si) contamination, causing EMF deviation-requires clean protection tubes.
Q:Can it be used in reducing atmospheres?
A:No-reducing atmospheres corrode PtRh alloy; use protective sleeves (e.g., inert gas protection).
Usage and Maintenance Instructions
Installation Specifications
1. Fully insert the protection tube into the measured medium (insertion depth ≥10× the tube diameter);
2. Ensure the positive (Pt13Rh) and negative (pure Pt) poles match the supporting instrument to avoid reverse connection;
3. Keep the lead away from high-temp areas-the armored part tolerates heat, but terminals must stay away from heat sources.
Usage Limitations
1. Only use in oxidizing/inert atmospheres (e.g., air, argon); do NOT use directly in reducing atmospheres (e.g., hydrogen);
2. Max continuous temp: 1300℃; max short-term (≤2h) temp: 1600℃;
3. Avoid strong vibration/shock to prevent wire breakage.
Daily Inspection
1. Regularly check if the protection tube is damaged/corroded-replace if cracks/deformation appear;
2. Check if terminals are loose/oxidized-clean/re-tighten if poor contact occurs;
3. If the supporting instrument displays abnormally, first check the thermocouple wiring/wire.
