Temperature

Temperature Sensors (RTDs and Thermocouples) are passive temperature measuring elements made to suit application from -200 to +1700°C. A Resistance Temperature Detector, RTD, provides a proportional change in resistance to temperature where a thermocouple generate a change in voltage for a given temperature by the reaction of two dissimilar metals in contact. These outputs are governed by standards like PT100 & PT1000 for RTDs and K & J for Thermocouples.

For resistance sensors (RTD) platinum resistors change their electrical resistance as a function of temperature. RTD, the most commonly used sensors in the industry, are suitable for applications between -200…+600°C. The accuracy classes A and B are available with a tolerance acc. to IEC 60751.

Thermocouples are made of two different conductors joined at the end. The temperature difference between junction, placed in measuring point (hot junction), and wire ends (cold junction), generate voltage proportional to the difference of temperature between these junctions. Thermocouples are suitable for the measurement of high temperatures, up to 1700°C. The accuracy classes 1 and 2 are available with tolerance acc. to IEC 60584.
