The Rupse A5-U280 Fuel Sender Unit is a versatile and high-performing boat tank sending water level sensor designed to provide accurate and reliable fuel level readings for various types of watercraft. This sensor is engineered to meet the unique demands of marine applications, ensuring optimal functionality even in harsh environmental conditions.
At its core, the Rupse A5-U280 Fuel Sender Unit is a float-type sensor, featuring a buoyant float that rises and falls with the fuel level in the tank. This float is connected to a resistor element, which changes its resistance value based on the fuel level. The sensor then translates this resistance value into a corresponding voltage level, which is sent to the boat's electrical system for interpretation.
This sensor is constructed using corrosion-resistant materials, making it well-suited for the corrosive marine environment. The sensor housing is made of durable ABS plastic, while the float is crafted from stainless steel to resist rust and corrosion. The sensor also features a waterproof connection for added protection against the elements.
The Rupse A5-U280 Fuel Sender Unit is designed to be easy to install and integrate with various boat electrical systems. It comes with a universal wiring harness, which includes a sender unit, a wiring connector, and a mounting bracket. The sensor can be mounted directly to the fuel tank using the provided mounting hardware, and the wiring connector can be connected to the boat's electrical system using standard marine wiring techniques.
The sensor has a wide operating temperature range of -20 C to 70 C (-4 F to 158 F), ensuring reliable performance in a range of environmental conditions. It also has a high accuracy of /- 2% FS, which translates to a fuel level reading accuracy of /- 1% for most marine applications.
In summary, the Rupse A5-U280 Fuel Sender Unit is a robust and accurate fuel level sensor designed specifically for marine applications. Its corrosion-resistant construction, easy installation, and wide operating temperature range make it an ideal choice for boat owners looking to accurately monitor their fuel levels and ensure safe and efficient operation of their watercraft.
