Its design allows for easy integration into existing burner setups, making it a popular choice for both new installations and retrofitting projects. The C7035A1023 is specifically calibrated to detect the unique ultraviolet signatures emitted by flames in coal, gas, and oil – fired burners. This ensures accurate and rapid flame detection, which is essential for preventing dangerous situations such as unburned fuel accumulation and potential explosions.
The sensor’s body is constructed with high – quality materials that can withstand the harsh environments typically associated with combustion applications. It is designed to operate reliably even in the presence of high temperatures, vibrations, and exposure to various contaminants.
4. Core Advantages and Technical Highlights
4.1 High – Sensitivity UV Detection
The C7035A1023 is equipped with a state – of – the – art ultraviolet sensing tube that offers exceptional sensitivity to the ultraviolet radiation emitted by flames. This high sensitivity enables it to detect even the faintest of flames, ensuring that the burner system can respond quickly to changes in the combustion state. Whether it’s a small pilot flame or a large – scale main burner flame, the sensor can accurately identify the presence of the flame and transmit the corresponding signal to the control system.
4.2 Robust Mounting Design
Featuring an integral nut for a 1 – inch sighting pipe, the C7035A1023 has a robust and secure mounting mechanism. This design not only simplifies the installation process but also ensures that the sensor remains firmly in place during operation, even in the presence of vibrations. The secure mounting is crucial for maintaining the sensor’s alignment with the flame, which is essential for accurate flame detection.
4.3 Protective Shield for Sensing Tube
To enhance the durability and reliability of the sensing tube, the C7035A1023 is equipped with a protective shield. This shield helps to prevent damage to the sensing tube from external factors such as mechanical impacts, heat, and chemical contaminants. By protecting the sensitive sensing element, the shield extends the lifespan of the sensor and reduces the need for frequent replacements, resulting in cost savings over time.
4.4 Weatherproof and Dustproof Design
Meeting the outdoor rain – tight requirements of Underwriters Laboratories Inc., NEMA 4, and NEMA 4X, the C7035A1023 is well – protected against environmental factors. It can withstand exposure to rain, dust, and other harsh weather conditions, making it suitable for use in both indoor and outdoor combustion applications. This weatherproof and dustproof design ensures that the sensor can operate reliably in a wide range of environments without the risk of performance degradation due to environmental factors.
4.5 Parallel Wiring for Difficult Sighting Applications
For applications where sighting the flame may be challenging, the C7035A1023 allows for wires to be connected in parallel. This parallel wiring feature provides flexibility in installation and can improve the sensor’s performance in situations where the flame may be obstructed or difficult to detect directly. By using parallel wiring, the sensor can still accurately detect the flame, ensuring the safe and efficient operation of the burner system.
4.6 High – Pressure Sealing
When correctly installed, the C7035A1023 can seal against pressures as high as 5 psi (34.5 kPa). This high – pressure sealing capability is important in applications where the burner system may be subject to varying pressures during operation. The ability to maintain a tight seal ensures that the sensor remains functional and reliable, even in high – pressure environments.
4.7 Field – Replaceable Sensing Tube
The field – replaceable ultraviolet sensing tube is a convenient and cost – effective feature of the C7035A1023. In the event that the sensing tube becomes damaged or its performance deteriorates over time, it can be easily replaced in the field without the need to replace the entire sensor unit. This reduces downtime and maintenance costs, as technicians can quickly and easily swap out the sensing tube and get the burner system back up and running.
5. Typical Application Scenarios
5.1 Power Generation Plants
In power generation plants, where coal – fired, gas – fired, or oil – fired boilers are used to generate electricity, the C7035A1023 is an essential component. It is used to monitor the flames in the burners of these boilers, ensuring that the combustion process is stable and efficient. By accurately detecting the presence of flames, the sensor helps to prevent boiler shutdowns due to flame failures, which can lead to costly disruptions in power generation.
5.2 Industrial Furnaces
Industrial furnaces, such as those used in the metalworking, glass manufacturing, and ceramic industries, often rely on the C7035A1023 for flame detection. These furnaces operate at high temperatures and require precise control of the combustion process to ensure product quality. The sensor’s ability to detect flames accurately and quickly allows for real – time adjustments to the fuel and air supply, optimizing the combustion process and reducing energy consumption.
5.3 Commercial Heating Systems
In commercial buildings, such as hotels, hospitals, and office buildings, the C7035A1023 can be used in gas – fired or oil – fired heating systems. It monitors the flames in the burners of these systems, ensuring safe and efficient operation. By detecting any flame abnormalities, such as misfires or incomplete combustion, the sensor can trigger alarms and shut down the system if necessary, protecting the building and its occupants from potential hazards.
