# Power Generation Thermocouple Wire

> Gas and steam turbines, boiler tubes, nuclear reactor sensing and waste-to-energy plants. Reliable temperature data for power generation assets.

## Applications

| Scenario | Requirement | Solution |
|---|---|---|
| Gas Turbine Exhaust | Continuous monitoring of exhaust gas temperature (EGT) for combustion tuning and blade-health trending. 500–650 °C, high-velocity gas stream. | Type K or N, φ0.5–1.5 mm |
| Steam Turbine Inlet | Superheated steam temperature at turbine inlet. 500–600 °C, high pressure. Long-term stability critical for efficiency calculation. | Type K, φ1.0–3.0 mm |
| Boiler Tube Wall | Metal temperature of water-wall and superheater tubes. Prevents over-firing and creep damage. Welded-pad or strap-on installation. | Type K, φ0.5–1.0 mm |
| Nuclear Reactor Core | In-core neutron flux and coolant temperature monitoring. Requires radiation-resistant alloys and rigorous material qualification. | Type N (low cobalt), φ0.25–0.5 mm |
| Waste-to-Energy | Combustion zone and flue gas temperature in municipal waste incinerators. Corrosive atmosphere — high chlorine and sulphur. | Type K with sheath, φ1.0–3.0 mm |

## Considerations

| Factor | Guidance |
|---|---|
| Long-term stability | Power generation thermocouples often remain in service for years between outages. Type N's superior drift characteristics make it the preferred choice for gas turbine exhaust — especially in combined-cycle plants. |
| MI cable for harsh environments | Mineral-insulated cable with SS316 or INCL600 sheath protects the conductors from combustion gases, fly ash and mechanical impact in boiler and turbine installations. |
| Redundancy | Critical turbine measurements use dual or triple thermocouples per location. Specify matched EMF output across sensors for valid inter-sensor comparison and voting logic. |
