Woodward 9905-020-P Magnetic Pickup Speed Sensor

Product Brief Introduction Passive magnetic pickup speed sensor, used to collect rotating speed pulse signals of prime mover gear wheels. It is a key measuring component of the closed-loop speed regulation system.
Tag:

Technical Specifications Passive magnetic pickup design without external power supply; wide operating temperature range; threaded installation structure; output sine wave pulse signal proportional to rotational speed.

Functional Features Non-contact speed measurement; excellent high vibration resistance; stable pulse output; simple structure with low failure rate.

Application Scenarios Diesel generator, gas engine, turbine rotating speed detection, prime mover speed feedback loop.

Performance Parameters Stable pulse signal output within the rated speed range; long mechanical service life, no wearing contact parts.

Structural Characteristics Threaded metal housing, built-in permanent magnet and induction coil assembly, cable outlet at the tail.

Working Principle When gear teeth pass the front end of the sensor, the magnetic flux of the internal magnetic field changes, inducing alternating pulse signal in the coil. The frequency of pulse signal corresponds to the rotating speed of the gear.
