Wema Water or Fuel Level Sensor 275mm 12/24 V

Product description:

The Wema S3 water or fuel level sensor with a length of 275 mm is a precise measuring device designed to monitor the liquid level in tanks, both water and liquid fuels. The product is widely used in the marine, automotive, agricultural industries, and in specialized vehicles where reliable liquid level reading is crucial for safety and operational efficiency. The sensor is mounted vertically at the top of the tank using standard mounting holes, allowing easy integration with existing installations. It operates on the principle of resistance change in the range from 240 to 30 Ohms, enabling compatibility with most analog indicators available on the market. The housing is made of materials resistant to corrosion and aggressive media, ensuring long service life even in harsh environmental conditions. The sensor supports a supply voltage of 12 V or 24 V, making it universal and compatible with various power systems. The device design minimizes the risk of blockage by contaminants, and the precise measuring mechanism guarantees stability and repeatability of readings. The Wema S3 sensor is often chosen by boat manufacturers, construction machinery, and commercial vehicle producers due to its reliability, ease of installation, and broad compatibility with indicator systems.
