A thermocouple is an excellent option for temperature measurement in various industrial applications. Thermocouples have two wire legs which are made from different materials. At one end, these legs are welded together (this creates a junction). 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. Thermal Devices is proud to offer a wide variety of thermocouples to be used in many different applications. Contact a Thermal Devices’ Sales Engineer for more information! Or, request a quote.
