Description
The Siemens QRB1A-A150B70A flame sensor is equipped with a photoresistive light-sensitive element that detects visible yellow flame radiation during the combustion of liquid fuel. Together with the boiler combustion manager, the sensor controls fuel supply to prevent emergency situations. The device is used to equip burners with intermittent operating modes. It is supplied with a power cord enclosed in a thermal protective sheath.
Features:
- detector with normal spectral sensitivity;
- degree of electrical protection against external influences – IP 40;
- compactness, simple installation;
- operating temperature from -20 to +60 °C;
- photoresistor for monitoring yellow flame radiation;
- 2-wire power cable 1500 mm with thermoplastic sheath;
- vibration-resistant mounting using a flange connection;
- registration of light with direct and lateral illumination (90°).
The sensor is capable of capturing a separate spectrum of extraneous radiation (from sunlight, lighting fixtures, etc.), which requires taking appropriate safety measures.
