2. Configurazione e installazione
Proper installation is crucial for accurate readings and long-term performance. Follow these steps carefully:
- Preparare il serbatoio: Ensure the tank is empty and clean before beginning installation.
- Determinare la posizione di montaggio: Select a flat surface on the top of the tank for mounting.
- Segna e fora: Use the provided gasket as a template to mark the center hole and screw holes. Drill the center hole with a 40mm opener. Drill smaller pilot holes for the screws.
- Measure Tank Depth: Measure the internal depth of your tank from the mounting surface to the bottom. Ensure at least 1 inch of clearance between the float retaining collar and the tank bottom. The sensor length should be appropriate for your tank depth.
- Install Gasket and Sensor: Place the gasket over the drilled holes. Insert the sensor into the tank, aligning the screw holes.
- Fissare il sensore: Fasten the screws in a sequence (e.g., diagonally) to ensure even pressure. Do not overtighten to prevent damage and ensure a leak-free seal.

3. Wiring and Operation
The KUS S3 sensor provides a 0-190ohm resistance output. It can be connected to compatible fuel or water level gauges that accept this signal range.
Istruzioni di cablaggio:
- Connect the sensor's signal wire (typically blue or orange) to the gauge's signal input.
- Connect the sensor's ground wire (typically black) to the battery negative terminal and the gauge's ground input.
- Connect the gauge's positive power input (typically red) to the battery positive terminal.
- If your gauge has a backlight, connect its positive wire (typically orange) to a switched 12V or 24V positive source.
Once wired, the sensor's float mechanism will move with the liquid level, and the connected gauge will display the corresponding level. The gauge provides a smooth and consistent sweep for accurate readings.

4. Manutenzione
The KUS S3 sensor is designed for minimal maintenance due to its robust SUS316 stainless steel construction. However, periodic checks can ensure optimal performance:
- Ispezione visiva: Periodically inspect the sensor for any physical damage, corrosion, or debris accumulation, especially if used in harsh environments.
- Pulizia: If necessary, gently clean the sensor rod and float with a soft cloth and appropriate cleaning solution for stainless steel. Avoid abrasive materials that could scratch the surface.
- Verifica della connessione: Assicurarsi che tutti i collegamenti elettrici siano sicuri e privi di corrosione.
5. Risoluzione Dei Problemi
If you encounter issues with your KUS S3 sensor, consider the following:
- Letture imprecise:
- Check for proper sensor length relative to tank depth.
- Verify electrical connections are secure and correctly wired.
- Ensure the float moves freely along the sensor rod without obstruction.
- Confirm the connected gauge is compatible with a 0-190ohm resistance signal.
- Nessuna lettura:
- Check power supply to the gauge and sensor.
- Controllare il cablaggio per individuare eventuali rotture o collegamenti allentati.
- Test the sensor's resistance output directly with a multimeter if possible.
- Leaks at Mounting Point:
- Ensure the gasket is properly seated and undamaged.
- Verify screws are tightened evenly, but not excessively.
