What instrument is used to measure Fuel Oil temperature?

The correct instrument for measuring fuel oil temperature is the RTD, or Resistance Temperature Detector. RTDs are widely used for temperature measurements due to their accuracy and stability over time. They function by measuring the change in electrical resistance of a metal as its temperature changes; typically, platinum is used for this purpose because of its predictable resistance characteristics across a wide temperature range.

In applications like monitoring fuel oil temperature, RTDs provide a reliable means of ensuring optimal performance and safety. They can offer precise readings, which is crucial for processes where temperature plays a significant role in efficiency and operational safety.

Thermocouples, while also effective for temperature measurement, might not offer the same level of accuracy as RTDs in certain conditions, particularly over extended periods. Conversely, pressure sensors and flow meters are specialized instruments designed to measure different parameters and are not suitable for determining temperature. Pressure sensors gauge the momentum of fluids or gases, while flow meters assess the rate of fluid movement, making them irrelevant for temperature measurements.
