System compatibility

5430-929 belongs to Woodward turbine governor system family,matched with 505,505E,MicroNet series controllers.Widely used in gas turbine,steam turbine and generator control cabinets.This is a discontinued legacy magnetic pickup speed sensor for power unit maintenance spare replacement.

Function

5430-929 serves as Woodward self-generating magnetic pickup speed sensor.It is installed near the rotating gear,generates AC pulse signal proportional to rotating speed when gear tooth passes the sensor head.The signal is transmitted to turbine governor for speed closed-loop control and overspeed protection.It adopts threaded body with lock nut,stable detection under high vibration and high temperature environment of rotating machinery.It is the core speed measuring component of turbine control system.

Installation

Screw 5430-929 into the mounting hole,adjust air gap between probe and gear tooth,lock the nut.Complete 2-pin connector wiring according to wiring drawing.Check air gap before commissioning.

Interface

‑2-pin plug connector

‑Threaded body with locking nut

‑Magnetic induction probe head

Circuit feature

Passive magnetic induction structure,no power supply needed,built-in vibration resistance design.Stable pulse signal output,strong anti-interference performance for power plant turbine site environment.

Feature

5430-929 is obsolete Woodward series spare part.Typical failures include signal weak,no pulse output,thread damage,connector poor contact.Check probe head and connector pins before replacement.This speed probe must match corresponding Woodward governor,direct substitution without inspection is not recommended.

Diagnostic

When speed loss,speed jump or no speed feedback occurs,the controller will trigger speed fault alarm.

Built‑in function

Rotating machinery speed detection,AC pulse signal generation,turbine overspeed protection signal acquisition,used as Woodward series magnetic pickup speed sensor spare replacement.

Product Brief

5430-929 is Woodward old turbine series magnetic pickup speed probe for gas/steam turbine generator sets and power automation equipment.Confirm governor model matching before ordering.ESD protection required during handling and installation.
