Types of Temperature Sensors
Types of Temperature Sensors Temperature measurement is essential in industrial processes, laboratories, and electronic applications. For this purpose, a variety of sensors are used, each with specific characteristics regarding accuracy, temperature range, stability, and cost. Among the most common are Type J and Type K thermocouples, PT100 and NI120 resistance sensors, and PTC sensors. 1. Type J Thermocouple The Type J thermocouple is composed of two metals: iron (Fe) and constantan (Cu-Ni). Typical range: –40°C to 750°CAdvantages: low cost, fast response, and suitable for dry, non-oxidizing environments.Disadvantages: iron oxidizes easily,…
