- Key functions & working principle
| Working Principle |
1. The sensor is threaded into the hydraulic/fuel line or engine oil gallery, with its diaphragm in direct contact with the pressure media (oil/fuel) |
| 2. Pressure applied to the diaphragm deforms the piezoresistive chip inside, changing its electrical resistance |
| 3. The sensor’s internal circuitry converts this resistance change into a proportional analog signal (0.5–4.5 V or 4–20 mA) |
| 4. The signal is transmitted to the ECU, which interprets the data to adjust system parameters (e.g., pump output, fuel injection timing) |
| 5. If pressure exceeds safe limits (e.g., hydraulic overload), the ECU triggers a warning light on the operator’s dashboard and may reduce engine power to prevent damage |
| Core Functions |
1. Real-Time Pressure Monitoring: Provides continuous data on hydraulic/fuel/oil pressure for ECU control |
| 2. System Optimization: Enables the ECU to adjust power output based on load demand, improving fuel efficiency and equipment performance |
| 3. Fault Detection: Alerts operators to abnormal pressure (e.g., low oil pressure, hydraulic overload) to avoid component failure |
| 4. Safety Protection: Triggers protective measures (power reduction, shutdown) for critical systems during pressure anomalies |
| 5. Diagnostics: Facilitates troubleshooting via Komatsu’s diagnostic tool (e.g., Komatsu IDSS) by storing pressure-related fault codes |
