In desperate search of information, concerning the fuel pump flow control (servo-valve and RVDT feedback) for the specific model MS7001B GE Turbine, which uses the Denison Hydraulics "fuel pump"...it is really an axial piston hydraulic pump. GE PART # 185-A1728-P001...DENISON CODE AND MODEL #'S M15-20925 AND PXX1223-609-R1P-X844.
Can anyone tell me anything about the speedtronic control board that converts the .7 to 3.5 V RMS RVDT output (8.4 VAC / 3khz excitatio) to whatever signal generated by the RVDT on the pump swashplate shaft(which corresponds to fuel-rate-of-flow), which is required to be used by the control (I assume a DC voltage to be used as in input to a summing junction)?
The RVDT's are a REALLY long lead-time, and I am looking at different sensors...and need to know what the RVDT AC signal is converted to, and why, so I can look at RVDT output converters to DC.
Thanks
