Product Details
The Siemens QRA73 UV Flame Detector is a specialized device used for detecting the presence of flames, primarily in industrial applications such as boilers, furnaces, and other combustion processes. It works by sensing ultraviolet (UV) radiation emitted by flames during combustion. The sensor is highly sensitive and capable of detecting flames at long distances and in harsh environments.Key Features UV Flame Detection: It detects ultraviolet radiation from flames, which is reliable in identifying combustion sources. Wide Detection Range: The QRA73 has an excellent detection range, capable of detecting flames at distances of up to 10 meters (depending on the flame size and intensity). High Sensitivity: It is designed to detect even small flames, making it suitable for use in applications with low levels of combustion activity. Weatherproof and Durable: It is built to withstand harsh industrial environments, including exposure to extreme temperatures and weather conditions. It has an IP65 rating, which means it is dust-tight and can withstand water jets from any direction. Quick Response Time: The sensor has a fast response time to detect flame presence, which is critical in safety-critical applications such as fire and gas detection systems. Output Signal: The QRA73 provides an electrical output signal (typically 4–20 mA or digital signal), which can be integrated into control systems for monitoring and safety functions. Low Power Consumption: The device is designed to operate efficiently with low power requirements, which is an advantage in energy-conserving systems.
