BRAHMA FC7/R PHOTOREISTOR
Genuine Italian Brahma FC7/R photocell flame sensor for burner monitoring with auto fuel shut-off on flameout. In stock at Nam Viet, best price, CO/CQ.
Product Overview
Brahma FC7/R Photocell Flame Sensor (photoresistor) is used for flame detection and monitoring in oil burner systems. The sensor detects light emitted by the flame, changes its electrical resistance according to the light intensity, and sends a signal to the burner control unit to identify the flame status.
The Brahma FC7/R photoresistor features lateral-side light detection and a red casing with a standard sensitivity range of 1.5–5.5 lux. It is suitable for maintenance and replacement applications in oil burner systems using compatible photocell flame sensors.

The FC7/R operates within a temperature range of −10°C to +60°C, with a maximum power dissipation of 500 mW and a maximum voltage of 320 V ACPK or DC. The sensor sensitivity range is 1.5–5.5 lux.
Operating Principle
The Brahma FC7/R uses a photoresistive element to detect light emitted by the flame inside the combustion chamber. When the burner establishes a flame, the light reaching the sensing element causes the electrical resistance of the photocell to change. This signal is transmitted to the burner control unit to detect the presence and status of the flame during operation.
The device functions as the flame sensing element, while control, monitoring, and safety functions are managed by the burner control unit. For maintenance or replacement, the correct sensor model should be selected according to the control unit used in the system.
The dimensional drawing helps verify the sensor construction and mounting position before replacement. The FC7/R has a 34 mm center-to-center distance between the two mounting holes, a Ø17.5 mm central opening, and uses Ø4 mm mounting screws.
Key Features
The Brahma FC7/R sensing element is designed to detect light from the side, making it suitable for burners where the flame observation point is positioned laterally. This design makes the FC7/R suitable for installation positions requiring flame monitoring from the side. When replacing the sensor, the light detection direction should be checked to ensure the correct model is selected for the system.
The Brahma FC7/R features a red casing, corresponding to the standard sensitivity level of this photocell series. The sensor has a sensitivity range of 1.5–5.5 lux, suitable for burner systems designed to operate with a photocell within this sensitivity range. When ordering or replacing the sensor, check the complete FC7/R model designation, casing color, and existing sensor information to ensure the correct product is selected.
Comparison of Brahma FC7/R and FC8/R Photocell Flame Sensors
The Brahma FC7/R and FC8/R are both photocell flame sensors used for flame detection in oil burners. Both red-casing models have the same sensitivity range of 1.5–5.5 lux, but they differ in their light detection direction.
| Feature | Brahma FC7/R | Brahma FC8/R |
| Sensor Type | Photocell / Photoresistor | Photocell / Photoresistor |
| Application | Oil burners | Oil burners |
| Sensitivity | 1.5–5.5 lux | 1.5–5.5 lux |
| Light Detection Direction | Lateral | Frontal |
The FC7/R is suitable for installations requiring light detection from the side, while the FC8/R is designed to detect light directly from the front. When replacing a flame sensor, check the existing sensor model, mounting position, light detection direction, and burner control unit to select the correct product.
Applications of the Brahma FC7/R Photocell Flame Sensor
The Brahma FC7/R is used in oil burner systems that require flame detection and monitoring during operation. It is suitable for:
- Oil burner systems using Brahma photocells;
- Flame sensor maintenance and replacement;
- Thermal equipment systems using oil burners;
- Applications requiring lateral-side flame detection;
- Systems requiring a photocell sensitivity range of 1.5–5.5 lux.
By providing a flame detection signal to the burner control unit, the FC7/R helps the system monitor the flame status throughout burner operation.
