11.1In preparation

Flame supervision: thermoelectric

Thermocouples and magnetic valves, and how to test drop-out.

This topic supports

  1. M11.1Explain how thermoelectric and flame-rectification flame supervision devices work, and test them.

The lesson text for this topic is being written. The learning outcomes above, and any artefacts below, show what it will cover.

Interactive artefact

Thermocouple flame supervision device

Heat produces millivolts, the magnet holds the valve open; remove the flame and watch it drop out.

Will demonstrate

  • Heat producing a voltage at the thermocouple
  • The magnet holding the valve open
  • The valve dropping out when the flame is lost

Planned. This interactive will appear here when it's built.
