Genuine Woodward variable reluctance magnetic speed pickup (MPU) (long-body 5/8-18 UNF variant cross-referenced to Woodward part number 5430-933, manufacturer marking MSC 401029-20) for precise shaft speed feedback to Woodward governors and digital turbine control systems. Passive, self-powered, zero-maintenance design for continuous duty on steam turbines running at 3000–3600 RPM; MSC 401029-20 is the most commonly ordered variant on Indian steam turbine governor retrofits and overhauls.

Primary Industrial Application

Primary speed sensing input for Woodward 505/505D/505E digital governors, 2301 and 7206 governor amplifiers, and standalone overspeed trip systems on Triveni, BHEL, Siemens, KKK, and Maxwatt steam turbines. The MSC 401029-20 / Woodward 5430-933 variant is the long-body, 5/8-18 UNF version most frequently specified on Indian steam turbine governor retrofits. Monitors turbine rotor speed via the governor gear wheel (tooth gear / flywheel) to provide closed-loop speed regulation, load control, and overspeed protection throughout startup, synchronisation, and full-load operation.
