Woodward 9010-00672 Speed Sensor / Magnetic Pickup

Product Brief Description

The Woodward 9010-00672 is a passive magnetic pickup (MPU) speed sensor designed for prime mover speed detection. It generates an AC sine wave signal by cutting the magnetic field of gear teeth, sending speed and timing signals to Woodward governors and control systems for precise engine or turbine speed measurement, overspeed protection and closed-loop speed regulation. It is widely used as spare replacement for generator and engine control packages.

Product Features

• Passive magnetic pickup design, no external power supply required
• Produces AC voltage signal proportional to gear rotational speed
• Robust stainless steel housing for engine room and harsh vibration environments
• Wide operating temperature range, resistant to oil, dust and moisture
• Threaded mounting body for easy air gap adjustment against gear teeth
• Shielded cable connection to reduce electromagnetic interference
• Compatible with Woodward 2301, 505, MicroNet and other governor platforms
• Simple structure, high reliability and long service life for continuous duty

Application Scenarios

• Diesel generator, gas engine and gas turbine speed monitoring
• Steam turbine, reciprocating engine overspeed protection systems
• Oil & gas engine-driven compressor and pump packages
• Cogeneration plants, emergency power units and marine generator sets
• Woodward governor closed-loop speed control and load regulation
• Retrofit and spare replacement of original speed sensing points

FAQ

Q1: Does this sensor need external power?

A1: No, it is a passive MPU, the signal is self-generated by magnetic induction.

Q2: What is the key installation requirement?

A2: Correct air gap between sensor tip and gear teeth must be set to get valid speed signal.

Q3: Which controllers can it work with?

A3: It matches Woodward speed governors including 505, 2301, MicroNet series.

Q4: Can it detect zero speed?

A4: No, passive MPU outputs signal only when the gear is rotating above minimum speed threshold.

Q5: Is this model obsolete?

A5: It is a legacy spare part, commonly available as surplus and refurbished units for field maintenance.
