De Dietrich 97580441 Ionisation Probe Electrode 90mm Gas Boiler Flame Sensor

Combustion Safety & Flame Sensing
Direct flame monitoring
for safe burner operation

This ionization electrode detects the presence of flame via electrical rectification across the combustion zone. The ceramic insulator isolates the electrical signal path while the heat-resistant sensing rod extends into the burner flame to deliver continuous feedback to the burner control unit.
