The EPSILON ES2 fuel level sensor is designed for high-precision fuel measurement (accuracy better than 99%) in reservoirs and vehicle fuel tanks. It can be integrated into fuel management systems (for monitoring fuel drains and refills) as well as GPS-based vehicle tracking systems from various manufacturers.
Key advantages over other manufacturers’ sensors:
Higher measurement accuracy thanks to increased sensor resolution and superior linear scale characteristics.
Modular design – the measuring head can be mounted or removed independently of the fuel probe, allowing quick replacement without the need to recalibrate the tank.
Short probe compatibility – can be used with tanks less than 30 cm deep.
Lightweight and easy installation – weighs only 300 g and requires minimal setup effort.
The measuring of the fuel level is provided by the measuring head with the probe, which is immersed into fuel. The probe is a coaxial capacitor formed by an aluminum tube (outer electrode) and insulated copper string (inner electrode). The necessary tension of the string is supported by a spring which is located in a contact connector of the probe. The mounting of the sensor is performed using self-drilling screws, flange fixing probe (together with a gasket) on the tank. Tightness of the measuring head is provided by O-ring seal located in the front groove. Protection of the interface cable from mechanical effects is provided by a flexible metal hose.
Safety of the sensor is provided with the application of:
intrinsically safe measuring circuit with normalized values of voltage, inductance, capacitance and resistance;
multi-layered security and front-end supply chain;
metal shell of the measuring head with a proper degree of protection (IP-68 according);
