Flame sensors monitor combustion in gas and oil burners, boilers and water heaters. Mounted in the flame path, they generate a small ionisation current or produce a UV signal that tells the burner control unit whether ignition has been established and the flame is burning safely. If the signal is absent or falls below threshold, the controller shuts the burner down. Correct operation of this component is essential for safe, reliable combustion.

Selecting the right sensor depends on the detection principle — ionisation rod or UV cell — as well as the electrode length, thread size, connector type and supply voltage required by the control box. Viewing angle and insertion depth also matter on oil burners. Parts in this section cover equipment from ACV, Baltur, Brahma, De Dietrich, Honeywell, Kromschroder, Riello and Siemens. If you have an order number from any manufacturer, use it in the search field to find the matching part.
