High Pressure Sensor for Caterpillar
This high pressure sensor monitors hydraulic system pressure in excavators, sending accurate readings to the machine's control system. Designed for Caterpillar E320C and E312C models, this sensor replaces OEM cross-reference numbers 157-3182 and 221-8859, ensuring reliable performance and precise pressure feedback.
Overview
This high pressure sensor is a direct replacement component for Caterpillar excavators, delivering real-time pressure data to the ECM for optimal hydraulic function. It is built for E320C and E312C machines and matches original specifications for seamless integration. This high pressure sensor ensures your machine maintains proper hydraulic pressure under demanding conditions.
Built For Performance

Good To Know
Q: Will this sensor fit my Caterpillar E320C with a different serial number? A: This sensor is designed for E320C and E312C models, but always confirm your machine's serial number and existing part number before ordering to ensure proper fit.
Q: What happens if I ignore a faulty high pressure sensor? A: A failing sensor can cause erratic hydraulic performance, reduced digging power, or engine derate, so replacement is recommended promptly to maintain machine productivity.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
