Product Introduction

This coolant level sensor is specifically developed for large excavators R300LC-9A, R480LC-9A, and R520LC-9A. It is an important safety monitoring component for the engine cooling system. The sensor is installed in the coolant expansion tank and continuously monitors the level of antifreeze. When the coolant drops below the safe level, it promptly sends alarm signals to the excavator ECU and the dashboard of the driver's cab, alerting the operator to replenish the coolant in time to prevent major failures such as engine overheating, cylinder seizure, and cylinder body damage caused by insufficient coolant. This sensor provides cooling protection for large mining and heavy-duty earthmoving excavators.

The sensor body is made of high-strength corrosion-resistant engineering plastic and is injection-molded as a single piece. It can be long-term immersed in antifreeze and is resistant to high and low temperatures, as well as chemical corrosion. It will not experience swelling or cracking. The threaded position is pre-coated with red high-temperature-resistant sealing glue, ensuring a tight seal after installation and preventing coolant leakage. The white original factory specification waterproof plug at the top has a self-locking catch, making installation and removal convenient. The internal sealing protection design of the plug can prevent construction mud, dust, and oil from entering the connector, maintaining stable signal transmission and reducing common problems such as poor contact and false alarms.
