🔍 Key Concepts

• Fuel oil temperature sensing methods used in marine gas turbines • Difference between temperature sensors (RTDs, thermocouples, transducers) and pressure probes • Where temperature for fuel control is usually measured in relation to fuel system, not compressor inlet air

💭 Think About

• Look at the illustration and ask: is fuel oil temperature related to air pressure at the compressor inlet, or to the properties of the fuel itself? • Which of the answer choices actually describes a device that directly senses temperature, not pressure or just an electrical configuration? • In typical marine gas turbine control systems, what type of sensor is commonly used for accurate, continuous fuel temperature measurement?

✅ Before You Answer

• Eliminate any options that mainly measure pressure rather than temperature. • Identify which option names a standard temperature-sensing element used in industry instrumentation. • Confirm that the chosen device can give an accurate, proportional electrical signal of temperature to the fuel control system.
