Technical Specifications Passive sensing without external excitation power; threaded metal housing; output sine wave pulse signal, frequency proportional to rotating speed. Operating temperature: -40℃ ~ +85℃.
Functional Features Non-contact speed measurement; excellent shock and vibration resistance; maintenance-free, no wearing consumable parts.
Application Scenarios Diesel genset, gas engine, steam and gas turbine speed feedback and overspeed monitoring loops.
Performance Parameters Stable pulse output within full working speed range; long service life without contact wear.
Structural Characteristics Precision machined threaded metal shell, built-in permanent magnet and induction coil assembly, shielded signal cable for noise suppression.
Working Principle When gear teeth pass the sensor tip, magnetic flux around the built-in magnet changes periodically. Flux variation induces sine wave pulses in the coil; pulse frequency reflects the actual rotating speed of the prime mover.
Installation Requirements Adjust air gap between sensor tip and gear teeth strictly per datasheet; tighten lock nut to prevent loosening caused by long-term vibration.
Usage Notes Avoid impact damage to sensing tip during transportation and installation; inspect air gap and cable insulation in routine maintenance.
