WebThermocouples are temperature measurement sensors that generate a voltage that changes over temperature. Thermocouples are constructed from two wire leads made from different metals. The wire leads are welded together to create a junction. WebPlatinum thermocouples (Type S) have one wire made from pure platinum and the other wire made from a platinum-rhodium alloy with 10% rhodium. They have characteristics similar to those of Type R devices, with a quoted measuring range of 0°C to +1750°C, measurement sensitivity of 10 μV/°C, and inaccuracy of ±0.5%.
