C7027 Series
UV Flame Sensors
High-performance ultraviolet flame detection for industrial burners. Ensure continuous safety supervision in gas, oil, and coal applications.
Series Overview
The C7027 Series consists of ultraviolet (UV) flame sensors designed for reliable flame detection in industrial combustion systems. These sensors detect ultraviolet radiation emitted by hydrocarbon flames and are commonly used in gas, oil, and coal burner applications where fast and dependable flame supervision is required.
C7027 UV sensors are typically integrated with industrial burner controllers to ensure safe ignition verification and continuous flame monitoring.
Functional Role in Combustion Safety Systems
Within a burner management system, the C7027 Series is used to:
- Confirm flame presence after ignition
- Continuously supervise flame stability
- Trigger immediate safety shutdown upon flame failure
- Provide reliable input signals to burner controllers
These sensors play a critical safety role and are essential components in industrial flame supervision circuits.
Key Differences
