CAT Oil Pressure Sensor Excavator Pressure Sensor for E307E200BE320C

This high-precision CAT oil pressure sensor serves as a core engine monitoring component, functioning as both a reliableexcavator pressure sensor and a sensitive oil pressure switch. Tailored for CAT construction machinery, it perfectly fits CAT E307, E200B, E320C excavators and features a fully sealed waterproof and oil-proof structure with high-sensitivity sensing chips. It delivers real-time, precise engine oil pressure detection and stable signal transmission, equipped with strong anti-interference and anti-vibration performance for harsh working environments. This essential excavator electrical accessory accurately captures abnormal oil pressure data and triggers timely fault alarms, effectively preventing engine abrasion, lubrication failure and burnout, and ensuring steady long-term operation of CAT excavators in mining and construction scenarios.

This oil pressure sensor is installed on the engine's main oil gallery to monitor oil pressure in real time:

1. Low Pressure Alarm Trigger: When oil pressure drops below the safety threshold (approx. 0.3–0.7 bar), the sensor contacts close, sending an alarm signal to the ECM and dashboard to prevent severe engine damage such as cylinder scoring or bearing burnout caused by insufficient lubrication.
2. Switch Signal Transmission: It features a mechanical diaphragm structure that opens/closes internal contacts under oil pressure, delivering stable and reliable signals adapted to the harsh high-vibration and high-oil conditions of construction machinery.
3. Fully Sealed Protection: The brass housing with high-temperature resistant seals resists oil corrosion and high-temperature environments, ensuring long-term stable operation.
