430-9455 Oil Level Sensor for Caterpillar | Aftermarket Replacement
430-9455 Oil Level Sensor for Caterpillar, featuring capacitive sensing and a 3-pin DT connector for reliable oil level monitoring in demanding heavy equipment and engine applications.
Product Description
The 430-9455 Oil Level Sensor is an aftermarket level sensor for Caterpillar engines and heavy equipment. It monitors oil level and helps provide a low-level warning when the oil level falls below the required range.
Caterpillar identifies 430-9455 as a hydrocarbon liquid level sensor and a robust level switch for engine and tank applications. It uses a capacitive sensing principle with no moving parts, which supports reliable operation in demanding equipment environments. The sensor is designed for applications where vibration and elevated temperatures are common.
The 430-9455 is an active sensor, so it requires an external electrical power supply. Cat also specifies a 3-pin DT connector, 7/8-14 SAE O-ring connection, and approximately 13.8-inch wire length. The sensor can be mounted vertically or horizontally, providing flexibility for different installation configurations.
Oil Level Monitoring for Heavy Equipment
Oil level monitoring is important for engine and equipment maintenance. A reliable level sensor helps the monitoring system identify a low oil level before it develops into a more serious maintenance issue.
The 430-9455 Oil Level Sensor is designed for oil applications and uses capacitive sensing technology. Unlike a mechanical float-type design, its sensing principle has no moving parts. This makes it suitable for applications where equipment experiences continuous vibration and high operating temperatures.
