The PSI flame viewing system is an integrated system comprising flame sensors and amplifiers electronically matched to ensure optimum performance for the ultraviolet spectrum of a hydrocarbon flame. This provides a reliable method of monitoring the flame in the combustion chambers of Ruston gas turbines.

The sensors will respond to UV radiation over a specific range 190 nm to 260 nm (1900 to 2600 angstroms) and feeds the signals back to the control unit. The control unit has four monitor lamps on the front panel which light when a flame is present in the combustion chamber. The PSI control unit also feeds the requisite logic signals to the other parts of the control cabinet.

The PSI control unit is a simple plug to plug exchange with the existing chassis 1. The flame viewing heads bolt to the existing flanges on the turbine and utilize existing cabling. Field personnel will find that, in day to day operation, nothing has changed except the systems requires less maintenance.

In over 15 years of operation, exhaustive tests by our customers have shown exceptional improvements in turbine start capabilties, and much reduced maintenance in terms of sight glass cleaning and viewing tube replacement. The unit has four major assemblies which are all field replaceable.
