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.

Temperature measurement of turbine blades
