Enerdrive 350mm 1-1/4" BSP 240-33Ohm Tank Level Sensor

Precision Fluid Monitoring for Marine, Caravan, and Off-Grid Applications

Maintaining an accurate read on your fluid reserves is critical for peace of mind while traveling or operating off-grid. This high-quality resistive tank level sensor provides a dependable and robust solution for monitoring fuel, water, and other compatible liquids in caravans, RVs, camper trailers, and marine vessels. Featuring a vertical rod-style design, it overcomes the common pitfalls of traditional mechanical swing-arm senders, ensuring you always know your exact tank levels without the risk of stuck components or erratic readings caused by fluid slosh.

Advanced Magnetic Reed Switch Technology

At the core of this fuel or water tank level sensor is a precision magnetic reed switch mechanism. As the sealed magnetic float travels along the shaft in tandem with the changing fluid level, it activates a series of internal switches. This action delivers a highly stable and continuous 240-33 Ohm electrical output to your monitoring system. By significantly reducing the number of external moving parts, this vertical float design delivers outstanding reliability, limits mechanical wear, and heavily extends the operational lifespan of the unit compared to generic standard senders.

Built Tough for Harsh Australian Conditions

Mobile and off-grid environments demand resilient equipment. Constructed entirely from marine-grade 316 stainless steel, this tank sensor provides exceptional resistance to rust and corrosion. Whether exposed to the chemical properties of diesel and petrol or the continuous moisture of freshwater storage, the heavy-duty housing remains uncompromised. Furthermore, the electronic components are securely sealed within the head unit, achieving a strict IP67 ingress protection rating. This shields the internal circuitry from dust, heavy condensation, and moisture, maintaining an accurate signal even in extreme marine or coastal conditions.

Key Features

• Marine-grade 316 stainless steel construction for ultimate corrosion resistance
• Frictionless magnetic reed switch technology delivers highly precise level tracking
• Industry-standard 240-33 Ohm resistance output, compatible with most popular analogue and digital gauges
• IP67-rated waterproof seal prevents moisture and dust ingress
• Simple two-wire connection (common negative and signal output) for straightforward installation
• Anti-explosion and chemical-resistant profile suitable for both fuel and water tanks

Seamless Installation and Retrofitting

Designed for straightforward top-mounting, this fuel or water sender features an integrated 1-1/4 inch BSP thread (approx. 31.8mm nominal). This allows the unit to easily screw directly into pre-tapped tank fittings, creating a secure and leak-free seal. The pre-terminated wiring harness exits through a sealed waterproof entry at the top of the sensor, ensuring your electrical connections stay dry and protected. If you are upgrading an older system or dealing with thin-walled plastic and metal tanks that lack an existing threaded port, this sensor pairs seamlessly with an optional 1-1/4 inch BSP to 5-hole flange adapter. This provides an easy retrofit solution to standard SAE or VDO 5-hole mounting patterns.

With its dedicated 350mm vertical profile, this specific model is tailored to provide maximum measurable range for matching tank depths, heavily reducing blind spots and unmonitored zones at the bottom of your reserve. This ensures you receive the most accurate data possible regarding your remaining capacity.
