Q

What type of temperature transmitter would be most suitable for measuring diesel engine exhaust and boiler stack temperatures and generates its own electromotive force?

🔍 Key Concepts

• Self-generating temperature sensors vs those that need an external power source • Which sensors are best for very high temperatures like diesel exhaust and boiler uptakes • Basic principle of a thermocouple junction compared with resistance-type sensors

💭 Think About

• Which of these devices actually produces its own small voltage (electromotive force) simply from two dissimilar metals at different temperatures? • Which listed devices are commonly used for extremely hot gas paths such as engine exhausts and boiler stacks on ships? • Which sensors in the options depend on a change in electrical resistance, and which depend on generating a voltage?

✅ Before You Answer

• Identify which option is specifically described in textbooks as self-generating (produces its own EMF) • Eliminate any sensors that work primarily on change of resistance rather than generated voltage • Consider which device type is routinely installed in exhaust manifolds and boiler uptakes in marine practice
