Wema Water and Fuel Level Sensor S3 0-190 Ohm 750mm

Product description:

The Wema S3-E750 water and fuel level sensor with a length of 750 mm is a specialized resistive transducer designed for precise measurement of liquid levels in tanks, both water and liquid fuels (e.g., diesel, gasoline). The device is widely used in the marine, automotive, agricultural industries, and in specialized vehicles where reliable liquid level monitoring is crucial for safety and operational efficiency. The sensor operates within a resistance range of 0–190 Ohm, making it compatible with most standard level indicators available on the market. Installation is done by screwing or bolting it to the top of the tank, and the "tube" type design minimizes measurement interference caused by waves or liquid movement. The housing is made of high-quality stainless steel, ensuring corrosion resistance and long service life even in harsh environmental conditions. The sensor is powered by 12/24V voltage, allowing universal use in various vehicle and stationary installations. Thanks to precise manufacturing and compliance with international marine and industrial standards, the product guarantees reliability and safety of use. The Wema S3-E750 sensor is often chosen by boat, yacht, construction machinery, and commercial vehicle manufacturers where quick and accurate liquid level determination in the tank is essential.
