Which symbol is used for Temperature Sensor/Primary Element?

• A. TE
• B. TV
• C. TIC
• D. FT

Answer: (A)

In instrumentation schematics, the device that directly senses the process temperature is identified as the Temperature Element. This two-letter tag, TE, is used to label the primary sensing element such as an RTD or a thermocouple. It distinguishes the sensor from other parts of the system that handle the signal after sensing—like transmitters, indicators, or controllers. Because TE literally designates the Temperature Element, it best matches the concept of the Temperature Sensor/Primary Element. The other symbols refer to different roles in the loop (indicating devices, controllers, or other process elements), so they aren’t used for the primary temperature-sensing element.
