Application Information
The KOMATSU 7861-93-3320 Temperature Sensor is an essential component of the machine’s electronic monitoring system. It continuously measures the temperature of the monitored system—such as the engine coolant, engine oil, or powertrain fluid depending on the application—and sends an electrical signal to the ECU or instrument panel. The control system uses this information to regulate machine operation, activate warning indicators, and protect critical components from excessive temperatures.
Manufactured to Komatsu OEM standards, the sensor is designed to withstand:
- Continuous engine operating temperatures
- High vibration environments
- Thermal cycling
- Exposure to oil and coolant
- Dust, moisture, and harsh jobsite conditions
- Heavy-duty construction and mining applications
A properly functioning temperature sensor helps maintain efficient machine operation, supports preventive maintenance, and reduces the risk of overheating-related failures.
