There is a table on the "GER3658D" regarding the MARK V Speedtronic GT Control System, on this table there is a description of the characteristics of MARK I, II, II ITS, IV, and V.

I just want to know what stands for "ITS" (MARK II ITS)

thanks

"ITS" stands for Integrated Temperature System. It included exhaust temperature control, overtemperature protection and combustion monitoring. It used the Intel 8008 processor.

 

ITS - Integrated Temperature Sensor

It was a digital, microprocessor-based control system module that was added to the Mark II product line late in the manufacturing period. It replaced a lot of potentiometers and some analog circuit cards in the Mark II.

It was primarily an exhaust temperature monitor (exhaust temperature control; exhaust spread monitor) which could also assist with the control of water- or steam injection for NOx reduction.

It had a digital readout and some thumbwheels that could be used to access parameters. Kind of crude, but, again, basically the first digital, microprocessor-based Speedtronic component used in the control of GE-design heavy duty gas turbines and a few GE-packaged aero-derivative turbines as well, as I recall.
