Wema Water or Fuel Level Sensor 450 mm 12/24 V

Product description:

The Wema S3 water or fuel level sensor with a length of 450 mm is a precise device designed for continuous monitoring of liquid levels in water or fuel tanks, both in industrial applications and in vehicles, boats, or construction machinery. This sensor operates on a resistive principle, generating a signal with variable resistance in the range of 240–30 Ohm, allowing compatibility with a wide range of level indicators. Installation is done by screwing it into the top part of the tank using a standard flange, ensuring tightness and stability of the installation. The housing is made of materials resistant to corrosion and the effects of fuel and water, guaranteeing long service life even in harsh operating conditions. The sensor is compatible with 12 V and 24 V systems, making it a universal solution for various types of vehicles and liquid storage systems. Thanks to its 450 mm length, it is suitable for medium and larger tanks, providing accurate level readings along the entire length of the probe. The product is especially recommended for applications requiring reliability, environmental resistance, and ease of integration with existing monitoring systems.
