Thermocouple Measuring principle
A thermocouple junction is a single point junction between two dissimilar metals. This junction creates a known millivolt level signal that changes as the process temperature increases or decreases. The millivolt signal is used as the temperature measurement input to a temperature controller.
Depending on an application's process temperature range, accuracy specifications, and material compatibility, our sensors are available in Type K thermocouples, Type J thermocouples, Type E thermocouples, Type T thermocouples, Type S thermocouples, Type R thermocouples, and other dissimilar metal combinations. ZYZL instrument manufactures thermocouple temperature sensors that can be designed with grounded or ungrounded junctions and housed in insulated sheath materials that are designed for best form fit in the applications.
