Doosan Daewoo sensor 856800-3130 plays a key parameter detection role in the engine electronic control system. It collects real-time signals such as fuel pressure, intake temperature or water temperature through built-in precision sensing elements, which are transmitted to the ECU (Electronic Control Unit) after signal conversion. It provides data support for fuel injection adjustment and ignition timing control, directly affecting engine power output and fuel economy, compatible with Doosan Daewoo DX300, DH225, DX500 series excavator engines.
The sensor features a stainless steel housing and ceramic sensing core, with IP67 protection rating, temperature resistance from -40℃ to 125℃, measurement accuracy error ≤±0.5%FS, and response time ≤10ms, ensuring stable operation under harsh conditions such as vibration (20G acceleration) and humidity. Its electrical interface adopts a waterproof plug design, with output signal of 0-5V analog or PWM digital signal, which is highly compatible with the original vehicle ECU, enabling plug-and-play without additional debugging during installation.
As a professional supplier, Ningbo Qiuning Trading Co., Ltd. provides both original and aftermarket 856800-3130 sensors. Original products strictly follow Doosan Daewoo technical specifications, each undergoing factory calibration and environmental testing, suitable for heavy-duty operation scenarios with extremely high requirements for detection accuracy; Aftermarket products pass 1000-hour stability tests, with key parameters (such as linearity and hysteresis) reaching over 95% of the original, priced at 55%-65% of the original, suitable for regular working conditions and budget-conscious customers, both with 6-month warranty.
