Wide Application Range

1. Full-function diesel generator OEM supporting: simultaneous coolant temperature display + 98℃ overheat automatic shutdown safety protection for M18 metric thread engine blocks
2. Old M18×1.5 dual-terminal alarm temp sender failure replacement: no temp reading, unstable gauge value, coolant leakage, missing high-temp fault alarm
3. Power rental & maintenance shop stock for standard gensets, marine engines, construction machinery with M18 cooling water port and safety auto-stop requirement
4. Retrofit complete safety monitoring system for silent generator sets, add 98℃ overheat auto stop protection

Common Equipment Failures Solved

• Cheap aftermarket dual temp sender resistance drift, water temp gauge value jumps randomly, alarm switch fails to trigger at 98℃
• Sensor brass housing corrosion & coolant leakage, engine overheat risk leading to cylinder head damage
• Incompatible third-party sender, analog temp gauge no display or serious reading deviation, DSE controller cannot detect high-temp fault signal
• Original KUS KE00122 damaged, need genuine M18×1.5 dual-terminal alarm temp sender direct replacement without wiring modification
• Generator engine block with M18×1.5 coolant port, requires both temperature display and 98℃ overheat automatic shutdown safety protection, single-terminal non-alarm sender cannot meet demand
