High pressure sensor 4436271 4355012

4436271 4355012

4436271 is a hydraulic pressure sensor (high-pressure switch/main pump oil delivery pressure sensor) specifically designed for Hitachi excavators. It is mainly used to monitor the pressure of the main pump hydraulic system and provide feedback to the controller to ensure safe and stable operation of the equipment. Common Symptoms of Malfunctions: 1. The instrument displays fault codes related to the pump pressure sensor (such as 11200-3/11200-4, etc.). 2. The whole machine moves slowly and weakly, with insufficient digging or walking power. 3. The engine speed cannot match the load normally, and the automatic idle is abnormal. 4. The hydraulic system responds slowly, and in severe cases, it enters the power limit protection mode. 5. Occasionally, overload alarms or abnormal pressure signals indicate that the sensor has a compact structure and sensitive response, and is a key component of the hydraulic system. It is recommended to replace it in a timely manner after damage to avoid affecting normal operation.
