Wema Water or Fuel Level Sensor S5 650 mm 12/24 V

Product description:

The Wema S5-A650 water or fuel level sensor is a precise measuring device designed to monitor liquid levels in tanks, both water and liquid fuels. With a probe length of 650 mm, the sensor is ideal for medium and large tanks typical for boats, yachts, construction machinery, commercial vehicles, and industrial installations. The device operates at 12 or 24 V, ensuring broad compatibility with electrical systems in vehicles and stationary setups. The sensor uses a 240–30 Ohm resistive output signal, allowing it to work with most standard liquid level indicators available on the market. Installation is done by screwing it onto the top of the tank using a standard flange, which guarantees a tight and durable connection. The housing is made of corrosion-resistant materials, enabling safe operation in humid and chemically aggressive environments. The Wema S5 sensor is often chosen by professional manufacturers and users due to its high reliability, ease of installation, and simple integration with existing liquid level monitoring systems.
