Thermocouples

Noble Metal Thermocouple Wire for High-Temperature Measurement

Accurate temperature measurement in extreme environments depends on materials that maintain stable thermoelectric performance over years of continuous operation.

Platinum and platinum-rhodium thermocouple wire are specified for applications where elevated temperatures, oxidation, and harsh operating conditions exceed the capabilities of base-metal thermocouples. Even slight variations in alloy chemistry or manufacturing consistency can introduce calibration drift, making precision manufacturing essential.

Sigmund Cohn Corp. manufactures noble-metal thermocouple wire with exceptional compositional control and dimensional accuracy to support reliable, repeatable temperature measurement throughout the sensor's service life.
