The LLS-2DF fuel level sensor is intended for continuous measurement of level of fuel, transformation of data to an analog, frequency or digital signal and signal outputs to the external device for remote observation of mobile objects by means of the system of monitoring. The LLS-2DF sensor consists of two basic elements: capacitive sensor and secondary converter. The sensor is executed in the form of the core having construct: tube core. Characteristics: supply voltage: from 8 to 40 V; consumption current: no more than 12 мА at 12 V, no more than 10 мА at 24 V; measurement error: no more than 0.5%; range of operating temperatures: from-45 to 80 °C; length of a measuring part: from 20 to 250 cm.
