Capteur d'ionisation De Dietrich 97943432

An ionisation sensor is a flame detection device used in gas burners to verify the presence of a flame by measuring electrical conductivity. As a critical burner spare part, it sends a signal to the control box to keep the gas valve open only when a flame is detected. This sensor is essential for safe burner operation, preventing gas release in the absence of ignition. When performing boiler maintenance or replacing faulty sensors, an ionisation sensor ensures reliable flame supervision and system safety, making it a vital component for any gas-fired heating equipment.
