platinum-rhodium thermocouple

Description :

3、 Three mainstream models (core selection differentiation)

1. S-type WRP (Platinum Rhodium 10 Pure Platinum, Single Platinum Rhodium)

Material: Positive electrode PtRh10 (10% rhodium+90% platinum), negative electrode high-purity platinum

• Temperature measurement: Long term ≤ 1300 ℃, short-term peak value 1600 ℃, range 0-1600 ℃

Advantages: National standard first level measurement benchmark thermocouple, with the highest accuracy and excellent oxidation resistance

• Working conditions: glass kiln, ceramic kiln, heat treatment electric furnace, metering calibration furnace

2. R-type WRQ (Platinum Rhodium 13 Pure Platinum)

Material: Positive electrode PtRh13 (13% rhodium), negative electrode pure platinum, thermoelectric potential 15% higher than S-type

• Temperature measurement: Long term 1400 ℃, short-term 1650 ℃, commonly used in European and American furnaces

• Working conditions: Precision sintering furnace, special metallurgy, imported kiln supporting equipment

3. B-type WRR (Platinum Rhodium 30 Platinum Rhodium 6, Double Platinum Rhodium)

Material: Positive PtRh30, Negative PtRh6, Two pole Full Platinum Rhodium Alloy

• Temperature measurement: Long term 1600 ℃, short-term 1800 ℃ (the highest temperature resistance in the entire series); The thermoelectric potential below 600 ℃ is extremely small, and there is no need for compensation wires at the cold end

• Working conditions: refractory material kiln, ultra-high temperature glass melting furnace, vacuum high-temperature furnace
