Thermocouples

Thermocouples for temperature measurement up to 1,700 °C

Thermocouples are temperature sensors that generate a voltage directly dependent on temperature. Compared to resistance thermometers, they are particularly suited for high temperatures up to 1,700 °C. Instrument designs from mineral-insulated sheathed cable are very resistant against extremely high vibration loads (depending on instrument model, sensor element and wetted materials). The accuracy classes 1 and 2 apply for thermocouples in accordance with IEC 60584 as well as the standard and special classes in accordance with ASTM E230.

What is green rot?

Thermocouples are subject to ageing and change their temperature/thermal voltage characteristic.
In Type K thermocouples high temperatures can result in substantial changes to the thermal voltage due to chrome depletion in the NiCr leg, leading to a l ... more
