Kromschroder Ionisation electrode rod 74462423

Kromschroder Ionisation electrode rod 74462423 is a 500 mm flame sensor for the ZSI-500/50 burner series. It is made of a special heat-resistant alloy and is resistant to combustion products and soot. This 100% original electrode monitors flame presence by conducting a small rectified current through ionized flame gases, ensuring safe burner operation.

Parts of this type are selected by electrode length, bend angle, insulator diameter, gap setting, mounting flange pattern, and the specific burner series they were shaped for. Before ordering, measure the electrode length and compare the mounting flange pattern to the existing part. Ensure the electrode gap relative to the burner earth is set correctly during installation.

Common failure modes include an eroded tip, cracked ceramic insulation, sooting that shorts the signal, and a drifting gap that lengthens ignition time or causes a false flame-out. When these occur, the burner control may lock out due to a weak or absent flame signal. Check the electrode tip condition, ceramic insulator for cracks or soot, and the gap setting.
