Technical Specifications Passive design with no external power supply; threaded metal housing; sine wave pulse output, frequency proportional to rotational speed; wide temperature range.
Functional Features Non-contact speed measurement, strong vibration resistance, simple and reliable mechanical construction without wearing parts.
Application Scenarios Diesel generator, gas engine and turbine speed feedback and overspeed protection loop.
Performance Parameters Stable pulse output within full operating speed range, long service life with zero contact abrasion.
Structural Characteristics Metal threaded housing, built-in permanent magnet and induction coil, shielded signal cable to suppress EMI noise.
Working Principle Gear teeth passing the sensor tip change magnetic flux, inducing alternating pulse signal in the internal coil. The pulse frequency reflects the rotational speed of the prime mover.
Installation Requirements Adjust the proper air gap between sensor and gear teeth, tighten lock nut firmly to avoid vibration-induced displacement.
Usage Notes Protect sensing tip from impact damage; inspect air gap and cable insulation regularly in routine maintenance.
