Woodward 8237-861

  • Product Name: Speed Sensor / Magnetic Pickup (MPU)
  • Product Description: A rugged magnetic pickup sensor for detecting engine/turbine speed. It generates an AC voltage signal proportional to rotational speed, used by Woodward governors and controllers for closed‑loop speed regulation.
  • Technical Specifications:
    • Output Signal: AC voltage (1–30 VAC RMS, 50–15,000 Hz)
