Honeywell LG1093AA24 UV Flame Probe
LG1093AA24 is a Honeywell LG1093 series UV flame probe. Applied to GE gas turbines, power plant boilers, and petrochemical heating furnaces, LG1093AA24 is a front-end sensing component for combustion safety protection. The body is equipped with a PTFE shielded cable, and the probe housing is made of stainless steel material, which can be directly installed at the observation port of the high-temperature and high-pressure combustion chamber. It is a key component of the unit’s flameout protection circuit.
Product function
- Flame UV signal acquisition: Sensing the ultraviolet light emitted by the burning flame, converting the optical signal into a weak electrical signal, and transmitting it to the rear flame amplification module.
- Flame detection: Real time monitoring of the ignition, normal combustion, and extinguishing status of the burner. The probe itself does not make logical judgments, and the signal is sent to the BMS system for processing.
- Source of ignition safety protection trigger: Once the flame is extinguished and there is no ultraviolet signal output from the probe, the BMS will receive the signal loss and trigger fuel cut-off and unit interlock shutdown to prevent the risk of gas leakage and explosion.
- Suitable for various fuel conditions of gas turbines and boilers, supporting flame detection of various fuels such as natural gas and fuel oil.
- On site collection under harsh working conditions: Directly facing the high temperature and high pressure environment of the furnace, complete on-site optical signal pickup, and transmit the signal to the processing unit inside the control cabinet through long-distance shielded cables.
