Rotor Sentry DAS can accommodate up to 32 pyrometers in any combination on multiple turbines. The software captures and displays one revolution of temperature data (thermal fingerprint) comprising approximately 3000 temperature readings equally spaced around the blade array.

One complete fingerprint from each pyrometer is sampled every few seconds and stored to disk at user-definable rates. The software can also monitor and store additional plant parameters such as:

	Gas Turbine Output Power
	Fuel Type
	Turbine Inlet Temperature
	Exhaust Gas Temperature

The trace clearly indicates that blades 6 to 9 are overheating - the first indication of a failure

Diagram showing the graphical display produced by Rotor Sentry Acquisition Software system - blades no.s 6 -9 clearly show an elevated temperature, the first indicator of potential failure.

Rotor Sentry Data Acquisition Software system controls the capture of the blade 'thermal fingerprints'.
