The IP40 enclosure rating and reliable screw terminal connections ensure longevity and consistent performance, even under fluctuating temperature conditions from -20C to +65C.
FAQs of Siemens Flame Sensor:
Q: How does the Siemens QRA Series Flame Sensor work in burner and boiler applications?
A: The QRA Series detects the presence of a flame in burners and boilers using its sensitive sensor and extracts a relay signal to indicate flame status. This ensures system safety by quickly signaling flame presence or absence.
Q: What are the installation requirements for the Siemens QRA Series Flame Sensor?
A: Installation involves vertical mounting and connection via screw terminals, suitable for standard applications as per the QRA model dimensions. The sensor should be mounted in a position where it has an unobstructed view of the flame.
Q: When should the Siemens QRA Series be used in industrial environments?
A: This sensor is ideal for any industrial process utilizing burners or boilers that require accurate flame detection and rapid response for safety shutdown or process monitoring.
Q: Where can the Siemens QRA Series Flame Sensor be deployed?
A: It can be installed in any industrial setting requiring flame detection in burners and boilers, from manufacturing plants to energy facilities, anywhere in India or globally.
Q: What is the benefit of using a flame sensor with an IP40 enclosure and die-cast aluminum housing?
A: The IP40 enclosure provides protection against solid objects, while the die-cast aluminum housing ensures the units resilience against mechanical stress, dust, and thermal fluctuationsvital for industrial reliability.
Q: How does the quick response time of less than one second enhance operational safety?
A: A response time of less than one second enables immediate detection of flame presence or absence, significantly reducing the risk of unmonitored combustion and greatly enhancing system safety measures.
