THERMOCOUPLES, THERMOCOUPLE ASSEMBLIES & REPLACEMENTS
Thermocouples are the most common, convenient, and versatile devices used to measure temperature. They convert units of heat into useable engineering units that serve as input signals for process controllers and recorders.
A thermocouple consists of a welded 'hot' junction between two dissimilar metals - usually wires - and a reference junction at the opposite end. Heating the 'hot' junction in the working environment produces a temperature gradient that generates an Electromotive Force (EMF). The EMF appears across the free ends of the thermocouple wires where it is measured and converted into units of heat calibration. Through selection of appropriate thermocouple wires and sheath components, thermocouples are suitable to be used in temperature ranges from (-200 to 2316) °C [-328 to 4200] °F.
Pyromation produces a wide range of thermocouples and thermocouple replacements for most market applications, including MgO (Magnesium Oxide), industrial and general-purpose types. We also make thermocouple assemblies for hazardous locations and other applications that require connection heads, protection tubes, thermowells and/or transmitters.
