Wide Application Range

1. OEM matching spare part for M18×1.5 thick thread ultra-heavy marine main engines & super large industrial diesel gensets, complete dual-function pressure monitoring + exclusive 1.5Bar low oil auto-shutdown safety system
2. Replacement for failed original KE21163 oil pressure sender: blank pressure gauge, irregular fluctuating pressure reading, oil seepage from thick thread housing, low oil alarm protection failure
3. Large marine overhaul & heavy mining power rental shop dedicated stock for ultra-large Cummins/Volvo marine generator sets and heavy construction machinery
4. Safety monitoring system retrofit for super heavy-duty generator units, add factory standard 1.5Bar low lubrication pressure automatic shutdown protection function

Common Equipment Failures Solved

• Cheap aftermarket sender unstable diaphragm & coil resistance, oil pressure gauge pointer jumps irregularly, DSE controller triggers false low-oil shutdown
• Inferior thin housing cracks under long-term heavy engine vibration, lubricant leakage leading to slow pressure loss and incomplete sensor signal
• Mismatched 0.8Bar/1.4Bar low alarm senders trigger protection too late, engine bearing & crankshaft damage under insufficient lubrication on large heavy units
• Original KUS KE21163 damaged, need genuine M18×1.5 dual M4 1.5Bar alarm oil sender direct plug-and-play replacement without wiring harness modification
• Ultra-large marine/mining heavy genset system requires dedicated 1.5Bar low oil auto-shutdown protection; standard 0.8/1.4Bar pressure sensors cannot meet large engine safety demand
