Kromschroder Flame sensor UVS10D0G1 84315200

Kromschroder UVS10D0G1 is a UV flame sensor designed for flame control of gas burners, used in conjunction with Elster Kromschroder automatic burner control units (IFS, IFD, PFS, PFD), flame detectors (IFW, PFF), or burner control units (BCU, PFU). It features an aluminum housing with an integrated heat guard and connection terminals. The sensor operates with a UV tube type P578, requiring a distance of 300–400 mm between the sensor and flame. It has an ambient temperature range of -40 to 80 °C, ingress protection IP65, and a weight of 390 g. The UV tube has a service life of approximately 10,000 operating hours.

When selecting a replacement flame sensor of this type, ensure compatibility with the burner control unit and that the UV tube type matches the original specification. The distance between the sensor and flame must be within the recommended range, and the cable gland diameter should accommodate the existing cable (7–13 mm). Verify the ambient temperature range and ingress protection rating meet the installation environment. Mounting typically involves securing the sensor in a fixed position with proper alignment to the flame.

Common failure modes for UV flame sensors include degradation of the UV tube, leading to reduced sensitivity or intermittent flame detection. This may cause the burner to shut down unexpectedly or fail to ignite. Check the sensor for contamination or damage to the UV tube, and verify the electrical connections are secure. If the sensor fails, the burner control unit may display a fault code indicating flame loss.
