WebFor example, a J-type thermocouple has one iron conductor and one constantan (a copper-nickel alloy) conductor. You can monitor thermocouples with versatile PC- based data acquisition systems. Thermocouples have some special signal conditioning requirements, which this note describes. Certain combinations of alloys have become popular as industry standards. Selection of the combination is driven by cost, availability, convenience, melting point, chemical properties, stability, and output. Different types are best suited for different applications. They are usually selected on the basis of the temperature range and sensitivity needed. Thermocouples with low sensitivitie…
