COGENG offers a specialized range of aftermarket and OEM-equivalent sensors and switches designed for Doosan heavy equipment, including wheel loaders, excavators, articulated dump trucks (ADTs), and forklifts. Their product focus in this category is on two critical sensing types:
Pressure Sensors – Monitor hydraulic, fuel, brake, or engine oil pressure. These sensors send real-time signals to the machine’s ECU (Electronic Control Unit) or dashboard, enabling pressure monitoring, warning alerts, and system protection. Common applications include main hydraulic lines, pilot circuits, transmission clutches, and common-rail fuel systems.
Temperature Sensors – Measure coolant, hydraulic oil, engine oil, or intake air temperature. Accurate temperature readings prevent overheating, optimize combustion, and protect hydraulic components. Typical sensors include coolant temp sensors (CTS), hydraulic oil temp sensors, and intake air temp sensors (IAT).
All COGENG Doosan sensors are built to meet or exceed original OEM specifications, featuring:
Plug-and-play connectors for direct replacement
Sealed construction (IP65/67) against moisture, dust, and vibration
Wide operating temperature range (-40°C to +125°C)
Compatibility with Doosan’s electronic diagnostic systems
These parts are ideal for servicing popular Doosan models such as DX series excavators (DX140, DX225, DX300), DL series wheel loaders (DL200, DL300, DL420), DA series ADTs, and older Doosan Solar models.
