Thermocouples, Temperature Probes
Thermocouples, fundamental temperature measurement components, convert temperature differences into voltage signals through the Seebeck effect. Temperature probes integrate sensors and protective structures, enabling wide-range sensing from -200°C to 2300°C. Together, these two product types form the temperature sensing layer for industrial automation, scientific research, and equipment monitoring.
