Digital data acquisition system for manitoring and remote testing of gas and steam turbine performance parameters

A digital data acquisition system for monitoring and remote testing of turbine performance parameters, said system comprising:

• a plurality of digital transmitters each adapted to be in contact with a corresponding pressure transducer;
• a plurality of instrumentation modules connected together by cables, each said module including a housing for containing some of said digital transmitters therein and each said module adapted to be connected to a computer for digital signal processing and data collection;
• a power supply module connected to one of said modules by a cable;
• and
• wherein said computer is adapted to be connected to another network.

A method for remote thermal performance testing of a gas or steam turbine, said method comprising the steps of:

• providing an array of digital transmitters in contact with corresponding pressure transducers with probes arranged in various locations in the turbine;
• connecting the digital transmitters together and to a local computer;
• connecting the local computer to a network;
• and
• conducting thermal performance testing from a remote computer connected to the network.
