What does the shop sell?

Spare parts for gas and oil burners and boilers: gas valves, nozzles, ignition electrodes and transformers, pressure switches, flame detectors, fuel pumps, servomotors and burner control boxes.

How large is the catalogue?

Description

This flame sensor is used for flame monitoring in burners that run on liquid fuel, including diesel and heavy oil. It sends an output signal to Siemens burner controls. The sensor has a fast response to flame loss. Its compact design makes installation straightforward.

Further details

Performance features	high sensitivity, stable operation, and reliability under long-term use
Safety Function	emergency shutdown of fuel supply on flame loss

Choosing and fitting

When selecting a replacement flame sensor of this type, compare the detection principle, spectral range, response time, cable length and connector type, and mounting sleeve arrangement with the original. The sensor must be compatible with the existing wiring and the burner control's input requirements. Position the sensor so it has an unobstructed view of the flame, and make sure the cable is not kinked or chafed.

Signs of failure

Common failure modes include a contaminated optical window, an aged photocell that produces a weakened signal, or a damaged sheath. If the flame is not detected within the safety time, the burner control initiates a lockout. Check the sensor window for dirt and ensure the cable is intact and not kinked.
