Woodward 1700-4131 Speed Sensor Assembly

Product Brief Introduction Magnetic pickup speed sensor assembly, used to detect rotational speed of prime mover gear and send pulse feedback signal to governor.
Tag:

Technical Specifications Passive magnetic pickup design, no external power required; threaded mounting structure, wide temperature range.

Functional Features Non-contact speed measurement, high vibration resistance, stable pulse signal output.

Application Scenarios Diesel generator, gas engine, turbine speed measurement closed-loop control.

Performance Parameters Reliable pulse output within rated speed range, no mechanical wearing parts.

Structural Characteristics Metal threaded housing, built-in permanent magnet and induction coil, tail cable outlet.

Working Principle Gear teeth pass the sensor tip and change magnetic flux, induce alternating pulse signal whose frequency corresponds to rotation speed.

Installation Requirements Adjust proper air gap between sensor and gear teeth, lock nut tightly against vibration loosening.

Usage Notes Protect thread during installation; periodically check air gap and cable wear.
