  • Key functions & working principle
Working Principle1. 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 Functions1. 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
