A Thermocouple is a temperature sensing probe consisting of the junction of two dissimilar metals which has a millivolt output proportional to the difference in temperature between the “hot” junction and the lead wires (cold junction).


STS utilizes the highest quality MgO (magnesium oxide) insulated metal sheathed cable available in all MgO’s. All cable meets or exceeds all applicable ANSI/ASTM standards. MgO insulated thermocouples have many desirable characteristics (i.e. fast response, compact size, broad temperature range, formability, weld ability, durability, accuracy, thermal shock and vibration resistance). These characteristics make the MgO an excellent choice for virtually all laboratory or process applications. The standard MgO configuration consists of ANSI/ASTM standard limits of error conductor material and standard (96%) pure insulation. Each catalog page details a variety of other configurations available.


Industrial thermocouples are used in high temperature applications, such as those listed below. Several calibrations are available as well as various mechanical configurations. Contact STS for technical assistance in choosing the correct unit for your application. From standard insulated elements to complete noble metal assemblies, STS provides temperature sensors for your high temperature applications.
