| Working Principle | 1. Pressure from the hydraulic/fuel system acts on the sensor’s diaphragm, causing it to deform slightly. |
| 2. The piezoresistive strain gauge on the diaphragm changes resistance proportionally to the deformation. | |
| 3. An internal signal conditioning circuit converts the resistance change into a calibrated analog (0–5V/4–20mA) or digital (CAN bus) signal. | |
| 4. The ECU receives the signal, interprets the pressure data, and adjusts engine/hydraulic operations (e.g., fuel injection timing, hydraulic valve opening) to maintain optimal performance. | |
| 5. If pressure exceeds safe limits (e.g., hydraulic overload), the ECU triggers a warning light on the operator’s dashboard and may limit machine power to prevent damage. | |
| Core Functions | 1. Real-Time Pressure Monitoring: Tracks hydraulic/fuel system pressure to ensure it stays within safe operating ranges |
| 2. ECU Feedback: Provides precise pressure data for engine/hydraulic system optimization – improves fuel efficiency and reduces component wear | |
| 3. Fault Detection: Alerts operators to abnormal pressure conditions (e.g., low hydraulic pressure, fuel rail pressure spikes) via dashboard warnings | |
| 4. Overload Protection: Enables the ECU to limit power or shut down non-essential systems during pressure surges, preventing damage to pumps, valves, and cylinders |
