Wide Application Range

1. OEM matching spare part for 1/8NPT thread Perkins diesel & marine gensets, complete dual-function pressure monitoring + exclusive 1.4Bar low oil auto-shutdown safety system
2. Replacement for failed original KE21101 oil pressure sender: blank pressure gauge, irregular fluctuating pressure reading, oil seepage from sensor housing, low oil alarm protection failure
3. Perkins engine overhaul & power rental shop dedicated stock for all types of Perkins silent generator sets and small marine auxiliary equipment
4. Safety monitoring system retrofit for Perkins generator units, add factory standard 1.4Bar 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 engine vibration, lubricant leakage leading to slow pressure loss and incomplete sensor signal
• Mismatched 0.8Bar alarm senders cause late protection, engine bearing damage under insufficient lubrication
• Original KUS KE21101 damaged, need genuine 1/8NPT dual M4 1.4Bar alarm oil sender direct plug-and-play replacement without wiring harness modification
• Perkins genset system requires factory standard 1.4Bar low oil auto-shutdown protection; universal 0.8Bar alarm pressure sensors cannot meet original equipment protection demand
