Woodward 8915-046 Speed Sensor Signal Conditioning Board

Product Brief Introduction The Woodward 8915-046 speed sensor signal conditioning board processes raw AC pulse signals from magnetic pickup speed probes. It reshapes waveform, amplifies weak signals and outputs standard pulse signals to governor and protection modules.
Tag:

Technical Specifications 24VDC auxiliary power, AC pulse input and square wave output. Operating temperature: -40℃ ~ +70℃.

Functional Features Weak signal amplification, waveform reshaping, noise filtering, open circuit fault detection.

Application Scenarios Speed signal conditioning for gas turbine, steam turbine and large diesel engine governing system.

Performance Parameters Wide input amplitude adaptation, low signal distortion, stable pulse phase.

Structural Characteristics DIN rail mounted signal board, signal running and fault LED indicators.

Working Principle Weak sine wave pulse from magnetic pickup enters the conditioning circuit. After amplification and shaping, it is converted into clean square wave pulse for control modules.

Installation Requirements Use shielded twisted pair for input and output pulse wiring, stay away from high-power cables.

Usage Notes Adjust signal threshold according to actual probe output amplitude, check signal waveform regularly.
