Suitable for the 339-8822 temperature sensor of Caterpillar 339882

Product Overview

Core Functions

1. Accurate Temperature Monitoring: Built-in high-precision NTC/PT thermistor probe, real-time and accurate collection of the temperature of engine coolant, hydraulic oil, exhaust gas and other media, providing continuous and stable temperature data for the ECU, ensuring the engine is always in the optimal operating temperature range.
2. Intelligent Condition Adjustment: The ECU automatically adjusts parameters such as fuel injection quantity, fan speed and hydraulic system pressure according to the temperature signal fed back by the sensor, optimizing fuel economy, improving power output efficiency, and avoiding cold engine wear and overheating damage.
3. Overheat Protection & Early Warning: When the medium temperature rises abnormally, the sensor sends an early warning signal to the instrument and ECU, triggering the dashboard alarm, reminding the driver to overhaul in time to prevent serious faults such as cylinder scuffing and crankshaft seizure caused by engine overheating, ensuring equipment safety.
4. Ready-to-Install: 1:1 reproduction of the original factory size, thread specification, electrical interface and harness length, fully matching the original Caterpillar mounting position and circuit system, no modification required, direct replacement of the original part, convenient and efficient maintenance.
