This durable water temperature sensor is an essential spare part for D2 type excavators. It tracks real-time coolant temperature changes and sends accurate data to machine control panels. Operators can instantly learn engine thermal conditions to prevent overheating faults and extend engine service life. Adopting high temperature resistant materials and tight sealing design, it resists liquid corrosion and frequent temperature fluctuation, running stably in various harsh construction scenarios for long-term engineering operation.
