Wide Application Range

1. OEM matching spare part for M18×1.5 mounting hole diesel gensets, heavy vehicles and marine engines, complete ultra-low speed accurate RPM real-time monitoring + overspeed runaway emergency shutdown safety system
2. Replacement for failed original KE10005 Hall speed probe: blank digital tachometer, lost low-speed pulse signal, irregular RPM fluctuation, controller overspeed protection failure
3. Generator maintenance shops, commercial vehicle repair stations, marine equipment overhaul factories general stock for low-speed precision speed measurement equipment
4. Safety monitoring system upgrade for silent diesel generator units, add stable near-zero RPM detection function unavailable for passive magnetoelectric sensors

Common Equipment Failures Solved

• Cheap aftermarket Hall probe low-sensitivity chip, no valid pulse signal at low idle speed, digital tachometer blank, DSE controller cannot recognize low RPM
• Inferior plastic housing cracks under long-term engine vibration, internal wire breakage leading to total loss of speed signal
• Narrow voltage adaptation range of generic sensors, signal distortion under 12V/24V voltage fluctuation, random RPM jump and controller false overspeed shutdown
• Original KUS KE10005 damaged, need genuine M18×1.5 three-wire Hall speed sensor direct plug-and-play replacement without wiring harness modification
• Diesel genset / heavy vehicle system requires stable near-zero low-speed rotation monitoring; two-wire passive magnetoelectric pickups cannot capture low RPM signals normally
