A thermocouple works on the Seebeck effect, where two dissimilar metals joined at one end produce a voltage proportional to the temperature difference between the hot and cold junctions. This voltage is measured to determine temperature.
According to IEC 60584, a Type K thermocouple has a temperature range of -40 to 1200 °C. However, exceeding this range can cause sensor degradation, so it is important to verify the specific model's limits.
Common standards include IEC 60584 for thermocouple tolerances and temperature ranges, ASTM A312 for sheath materials for operating pressure, and IEC 60529 for ingress protection. These are reference standards; always confirm compliance with the manufacturer.
Consider factors such as temperature range, accuracy class, response time, probe diameter and length, sheath material, connection type, output signal, and environmental conditions (e.g., pressure, ingress protection). Verify all parameters with the supplier for your specific use case.
