Fuel Level Sensor EPSILON ES

Sensor Description

Inside the sensor measuring head is the level converter, digital signal processing circuit, the data exchange device, voltage regulator and circuit, providing the necessary protection for the input and output circuits. Connection with external devices is provided via cable.

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 to GOST 14254);
• compound filling the shell of the measuring head.
