Wema Fuel Level Sensor S5-A320, 240-30 Ohm, Stainless Steel

Product description:

The Wema S5-A320 Fuel Level Sensor, 240-30 Ohm, is a precise device designed to monitor fuel quantity in tanks, most commonly used in boats, yachts, specialized vehicles, and industrial machinery. Its construction is based on a proven float mechanism that moves along a steel rod, changing resistance within the 240–30 Ohm range, allowing compatibility with most standard fuel level gauges. The stainless steel housing provides high resistance to corrosion, fuel exposure, and harsh environmental conditions, including moisture and salinity. The sensor is mounted by screwing it onto the top surface of the tank using a standard 5-hole flange, enabling easy replacement or servicing without the need to empty the tank. The sensor features high measurement accuracy and stable readings, with a design that minimizes the risk of float jamming. The product is suitable for both new installations and as a replacement in existing fuel monitoring systems, ensuring compatibility with a wide range of gauges and control panels.
