Turbine Sentry - Combustion Turbine Blade Temperature
Turbine Sentry
Turbine Sentry - System Overview
An overview of the complete system and how this system is of benefit to gas turbine operators.
A typical system comprises three parts:
Blade Sentry - Measurement Pyrometer
The non-contact thermometer is mounted through the gas turbine casing and measures the temperatures of individual rotor blades.
Rotor Sentry - Data Acquisition System
The DAS logs individual blade temperature readings taken by the measurement pyrometers, samples and processes the data for use by the data analysis software, Data Sentry.
Data Sentry - Data Analysis Software
This powerful pc-based software utility has all the tools and functions necessary to obtain a complete picture of how efficiently the gas turbine is running, as well as identifying potential problems at an early stage.
- Modular Design - subsystems design simplify installation and maintenance
- Rotor Sentry - single data processing unit, field-expandable to handle up to 32 turbines
- Performance - 30 readings per blade for high resolution blade temperature profiles
- Reliability - electronics separated from harsh engine environment by fiber optic link
- Ease of Use - menu structured PC control,running under Windows NT®, for automatic or manual operation
- Compatibility - exported tabular data can beused in any spreadsheet program accepting ASCII file format
- Certified - Pyrometer manufactured to ATEX directive 94/9/EC (CE Ex II 3 G T6)
- Continuous on-line measurement of individual blade condition
- Increased efficiency through improved engine firing rate
- Detection of blocked cooling channels
- Reliable, accurate blade row temperature
- Early warning of potential blade failure caused by over-temperature operation
- Continuous monitoring of blade coating condition
