The T5.4 thermocouple is a temperature-sensing probe used in LM2500 gas turbines to measure exhaust gas temperature (EGT). The label T5.4 refers to its specific position in the turbine\'s exhaust thermocouple array—zone T5 (turbine exhaust), sensor 4. These sensors are part of a system that monitors thermal conditions at multiple points in the exhaust stream.

This thermocouple operates in high-temperature environments, withstanding continuous exposure up to approximately 1100°C. It is built to maintain accuracy and reliability under the thermal stress and vibration typical in gas turbine applications.

T5.4 thermocouples are often used with flexible

harness systems. This allows operators to replace individual probes without removing the entire harness, improving maintenance efficiency and reducing downtime.

By providing real-time exhaust temperature data, the T5.4 thermocouple supports engine control, performance optimization, and safety monitoring in industrial gas turbine operations.

The LM2500+G4 SAC 50Hz Combined Cycle 2x1 is a high-performance gas turbine system designed for large-scale, high-efficiency power generation, particularly suited to the needs of oil and gas operations. This configuration links two LM2500+G4 gas turbines with a single steam turbine in a combined cycle layout—capturing waste heat from the gas turbines to produce steam and generate additional power. This approach significantly improves overall thermal efficiency while maintaining operational flexibility.

The Single Annular Combustor (SAC) with optional water injection helps the system meet emissions rules while keeping combustion stable and efficient. The LM2500+G4 improves on the previous +G4 model by increasing airflow, using better materials, and adding improved cooling. This allows it to produce about 10% more power without reducing the lifespan of critical hot parts. It can be equipped with either a two-stage or six-stage power turbine to fit different needs. Even with the higher power output, the +G4 keeps its modular, two-spool design, which makes maintenance easier and ensures reliable performance in many environments.

In the 2x1 configuration, the system delivers approximately 41% more power than a single gas turbine unit. The use of combined cycle technology ensures better fuel utilization, helping to reduce overall emissions and lower lifecycle operating costs.

The LM2500+G4 SAC 50Hz Combined Cycle 2x1 offers higher power, improved efficiency, and a flexible design, making it well-suited for large-scale oil and gas operations that demand reliable and efficient power generation. Its “50Hz” designation means the turbine is specifically optimized to supply electricity to grids operating at 50 cycles per second, ensuring seamless integration with regional power systems.
