Exotronic 0 - 500mm Water Tank Level (Pressure) Sensor

Precision Hydrostatic Level Transducer for Water and Fuel Tanks

Reliable 0–500mm Range with Ceramic Sensing and Stainless Steel Durability

The Exotronic 0–500mm Water Tank Level Sensor uses a dry ceramic capacitive pressure element and an application-specific integrated processor to deliver consistent, accurate level readings in freshwater, diesel, and petrol tanks. Unlike generic float switches or resistive probes, this hydrostatic transducer has no moving parts to jam or corrode, reducing the risk of sudden failure in remote or mobile installations.

With a 304 stainless steel body and IP65-rated ingress protection, the sensor withstands shock, vibration, and temperatures from -40°C to 85°C. The G1/4 (~12.9mm) threaded connection with O-ring seal ensures a secure, leak-proof fit, while the 3-metre cable with pre-crimped ferrule terminations simplifies wiring to monitoring systems.

Seamless Integration with Victron and Simarine Ecosystems

This sensor outputs a 1–5VDC signal proportional to liquid level, making it directly compatible with Simarine SI-SCQ25T and SI-ST107 modules, as well as Victron Cerbo GX and Ekrano GX via the GX Tank 140. Real-time tank data helps you manage water consumption, schedule refills, and avoid running dry—whether you’re on a passage, off-grid, or managing a remote site.

Key Features

• ±0.5% full-scale accuracy for precise level monitoring
• Dry ceramic capacitive sensor resists corrosion and media compatibility issues
• 304 stainless steel housing with IP65 protection for harsh environments
• Wide 8–30VDC supply range suits 12V and 24V systems
• Overload capacity up to 10× rated range for surge resilience
• 3-wire connection: power, ground, and 1–5VDC signal output
• Compatible with freshwater, diesel, and petrol

Applications Where Reliability Matters

• Marine and boat water tanks—maintain supply on extended voyages
• RV and caravan freshwater systems—monitor levels without opening hatches
• Off-grid tiny homes and cabins—optimise water usage and pump cycling
• Industrial and fuel storage—dependable readings for diesel and petrol tanks

Installation and Wiring

The sensor installs via a standard G1/4 (~12.9mm) threaded port. Connect the red wire to 8–30VDC positive, black to system negative, and yellow to the voltage sense input of your monitor. The 3-metre cable can be extended or shortened to suit your tank depth and routing requirements.
