Technical Specifications Passive magnetic pickup, sine wave frequency output, no external power supply required. Operating temperature: -50℃ ~ +120℃.
Functional Features Non-contact speed measurement; high vibration resistance; long service life.
Application Scenarios Generator engine shaft speed detection, turbine rotational speed monitoring.
Performance Parameters Stable signal output in wide speed range, strong anti-interference capability.
Structural Characteristics Threaded metal probe, stainless steel housing, internal permanent magnet and coil assembly.
Working Principle The gear tooth cuts the magnetic field of permanent magnet, induces AC voltage signal in coil, signal frequency is proportional to shaft rotating speed.
Installation Requirements Adjust air gap between probe and gear teeth strictly according to datasheet, use shielded twisted pair cable.
Usage Notes Prevent probe collision with gear; check cable insulation regularly; keep probe surface clean.
