Coolant Level Sensors - Engine Room Consumables and Spares
Coolant level sensors monitor the coolant level in marine diesel engine expansion tanks, radiators, or cooling-water circuits. They provide low-level alarms or shutdown signals to the engine monitoring and protection system.
ProShipWorks provides end-to-end support to source and supply Coolant Level Sensors for marine vessels, ship operators, industrial facilities, maintenance teams and procurement departments.

Standards, Certifications & Class Approval
Review the available standards and approval information relevant to the product. Actual certification, material traceability, inspection and classification requirements depend on the product type, intended application and purchasing specification.
| Applicable Standards & Certification | Certification and environmental requirements depend on the engine and vessel installation. Marine applications may require IEC 60092 equipment suitability, EMC compliance, and OEM or classification-society approval. Verify the exact sensor documentation before procurement. |
|---|---|
| Class Approval | There is no universal class approval for all coolant level sensors. Approval may be required by DNV, ABS, Lloyd's Register, Bureau Veritas, or ClassNK when the device is part of a classed engine monitoring or shutdown system. |
Installation, Maintenance & Safety Information
| Installation Notes | Confirm the OEM part number, sensing technology, thread, electrical connector, switching logic, and supply voltage. Isolate and depressurize the cooling system before removal. Install with the correct seal and orient the sensor according to the manufacturer instructions. |
|---|---|
| Maintenance Tips | Inspect connectors, wiring, mounting threads, and seals during engine maintenance. Check for coolant leakage, contamination, corrosion, and false alarms. Test the alarm and shutdown circuit at the intervals specified by the engine manufacturer. |
| Safety Notes | Allow the engine and coolant to cool before servicing. Depressurize the cooling system and use appropriate PPE because hot coolant can cause severe burns. Do not bypass a low-coolant alarm or install a sensor with incompatible electrical ratings. |
