Technical Specifications Output: Sine wave variable reluctance signal; Frequency range:0 ~ 10 kHz; Operating temperature:-40 °C ~ +150 °C; Thread size: 3/4-16 UNF; Housing material: 416 stainless steel.
Functional Features No external power supply required; wide operating temperature; rugged vibration-resistant construction; simple installation.
Application Scenarios Gas/diesel engine speed measurement, turbine speed pickup, overspeed protection system, Woodward governor speed input.
Performance Parameters Output amplitude: >0.5V peak at minimum speed; Air gap range:0.25 ~ 1.25 mm; Working life: long-term continuous operation.
Material Composition Stainless steel housing; permanent magnet; induction coil; PTFE insulated lead wire.
Structural Characteristics Threaded cylindrical probe; hexagon for wrench tightening; integrated lead cable.
Working Principle When gear teeth pass the sensor probe, magnetic flux changes, inducing AC sine wave voltage signal in internal coil. Signal frequency is proportional to rotational speed.
Installation Requirements Screw into threaded mounting hole; adjust air gap between probe and gear tooth; secure lock nut.
