Temperature Sensor & Transmitter CAD Blocks (RTD, Thermocouple, Thermowell)

When you’re drafting P&ID, instrumentation layouts, or piping details, using the correct temperature measurement symbols and blocks saves time and keeps your drawings consistent. This CAD set covers common field instruments used for temperature monitoring and control—ideal for mechanical, process, and utility projects.

What you can represent with this set

  • Temperature sensors (typical RTD / thermocouple probe styles)

  • Temperature transmitters and connection head variations (different head shapes and orientations)

  • Thermowell / protection tube style details (probe protection for pressurized lines)

  • Inline / inserted mounting examples on piping (typical installation views)

  • Probe stem / extension options for different insertion lengths and site conditions

How to use it in real drawings

  • On P&ID, tag instruments clearly (examples: TE, TT, TI) to match your instrument index.

  • On piping/isometric, show thermowell + probe when the line is pressurized or high-velocity, and show direct insertion only when allowed by spec.

  • Keep one consistent block style for all sheets so construction and commissioning teams can read it fast.
