Fuel Level Sensor EPSILON ES

Operation principle

Sensor probe immersed in the fuel acts as a variable capacitor, whose capacity is linearly dependent on the level of its filling with fuel.

The sensor measuring head performs a linear transformation, capacity of the probe into a digital code-level fuel, processing of the digital data by averaging the results of measurements, temperature measurement of fuel tank and issuance of data in a uniform protocol for EDE RS-485 or RS-232 or analog signals (only the level), depending on the model.

Data on the fuel level may be issued in the form of 10-and 12-or 16-bit value, the temperature data — in the form of an 8-bit value.

To determine the amount of the controlled fuel calibration procedure must be carried out on the fuel tank, in which we establish the relationship between the amount of fuel level to the sensor code level.
