Thermocouples

Type J thermocouple is a very common and general purpose thermocouple. It has smaller temperature range and a shorter lifespan at higher temperatures. It consist of positive leg made of an Iron wire and negative leg made of an Constantan ( Copper-Nickel ) alloy wire.

RTD (Resistance Temperature Detector) and thermocouple are both temperature sensors, but they work differently and have different strengths and weaknesses. RTDs measure temperature by sensing the change in electrical resistance of a material, typically platinum, as it heats up.

Type S thermocouples have an operating temperature range, described in the standard DIN EN 60584, from 0 to +1600°C (in class 1) and a limiting deviation of ±1.0°C or[1 + (t - 1100) x 0,003] °C. The temperature range of a type S thermocouple is 0 to +1600°C in class 2.
