Wema Water or Fuel Level Sensor S3 300 mm 12/24 V

Product description:

The Wema S3 water or fuel level sensor with a length of 300 mm is a precise measuring device designed to monitor liquid levels in tanks, suitable for both water and fuel applications. It is widely used in the marine, automotive, agricultural industries, and liquid storage systems where reliable medium level control is required. The sensor operates on the principle of resistance change within the range of 0–190 Ohm, allowing compatibility with most analog gauges available on the market. Installation is vertical, usually from the top of the tank, using a standard mounting flange with a gasket, ensuring tightness and operational safety. The housing is made of corrosion-resistant materials such as stainless steel, guaranteeing long service life even in harsh environmental conditions, e.g., contact with seawater or fuels. The sensor is compatible with 12 V and 24 V installations, making it a universal solution for various types of vehicles and vessels. Thanks to its simple design and reliability, the device minimizes the risk of failure and requires only periodic mechanical condition checks and electrical connection inspections. The Wema S3 300 mm sensor is often chosen by boat manufacturers, construction machinery producers, and individual users who expect a precise and durable solution for liquid level monitoring.
