Hardware Specifications

Process Control and DCS Characteristics

• 4-20 mA HART loop protocol: The sensor integrates with EG1033 amplifier modules to facilitate signal conditioning, ensuring flame status data is compatible with 4-20 mA control loop input requirements.
• FOUNDATION Fieldbus / Profibus PA connectivity: Integration with the amplifier allows flame intensity and fault signals to be relayed to DCS platforms, maintaining high-speed deterministic reporting for turbine safety logic.
• Channel-to-channel isolation: The detector and associated amplifier cabling are designed with high-integrity shielding to prevent electrical noise coupling, maintaining isolation between the flame monitoring circuit and external electromagnetic interference.
• Cold junction compensation (CJC): The unit is engineered for operation in high-temperature turbine environments, ensuring signal stability and spectral sensitivity consistency, which is fundamental for accurate UV flame discrimination in presence of black body radiation.

Frequently Asked Questions

Q: Is this sensor compatible with all GE gas turbine configurations?

A: The LG1093 series is not optimized for GE/NP DLE (Dry Low-NOx) gas turbines, which require specific pre-selected units. Consult turbine OEM specifications before installation.

Q: Can this sensor be used in hazardous atmospheres?

A: Yes. This model holds CE, ATEX (EEx d IIA T3), and Factory Mutual (Class I, Div 1 and 2) approvals for operation in explosive atmospheres.

Field Installation Guidelines

• Mounting: Secure the sensor to the combustion chamber viewing port, ensuring the flange is seated correctly against the 428 mbar rated viewing window. Utilize the provided 0.14-inch wide flange for structural alignment.
• Grounding: Ensure the armored cable sheath is bonded to the turbine chassis at the amplifier entry point. A low-impedance connection is mandatory for EMC compliance and suppression of induced electrical transients.
• Wiring: Route the 2-conductor armored cable through protective conduits. Maintain strict segregation from high-voltage ignition leads to prevent capacitive noise coupling into the flame signal line.
