Type R and S Thermocouple - Items tagged as "Flat-pin"
ThermocoupleTypeRandSare made from Platinum and Rhodium thermocouple alloys and designed to be extremely stable with a temperature range up to 2,700°F (1480°C). Type R and S are resistant to oxidation in air although reducing atmospheres can be especially damaging.
Overall Temperaturerange is -58 to 2,700°F(-50 to1480°C). This wide temperature range and high level of stability provides excellent overall application opportunities, although most times R and S thermocouples are utilized at temperatures of 1800°F (1000°C) and higher due the thermocouple alloy having lowper degree milivolt output at lower temperatures,
This low output along with the high materials cost reduces the opportunity to use this thermocouple in general purpose applications
Type R and S is not recommended in reducing atmospheres, unless the thermocouple alloys are protected with a gas-tight ceramic tube and a secondary tube of alumina, silicon carbide, or a metal outer tube
Type R has 3% more Rhodium and it offers improved stability and a slightly higher temperature range than Type S
Type R can deliver 15 percent more millivolt output than Type S.
Type R compostion is positive wire Platinum with 13% Rhodium, the negative wire is 99.99% Platinum
Type S content is positive wire Platinum with 10% Rhodium the negative wire is 99.99% Platinum
Connector pinsandExtension cables are made with a specially designed compensating alloy to reduce cost although at the same time ensuring the accurate transfer of the thermocouple signal
