Sensor is purposed for fuel level measurement in containers and fuel tanks of vehicles. Sensor can be used with equipment that supports unified communication protocol Epsilon Data Exchange. Sensor has the electronic galvanic isolation through interface and power-supply circuits. Fuel level measurement is provided by a measuring head together with the probe submerged in fuel, which acts as a condenser, which capacity linearly depends on a fuel level in a tank. EPSILON ES2-H digital RS-232,capacitive fuel level sensor is designed to measure fuel level in vehicle tanks and reservoirs with high precision (99% accuracy).
Main advantages:High-resolution of the sensor, linearity, temperature stability;
Calibration table inside the sensor head. Allows transferring data directly in liters;
Galvanic isolation. Protects sensor head from power surges;
Monolith construction;
Wide range of possible probe length from 15 to 300 cm;
Ease of installation. Any hack saw can be used to cut the probe.
Additional features Model ES2-H sensors provide frequency interface (signal outputting from 500 to 1500 Hz frequency with linear frequency dependence vary with measured level of fuel). Also, model ES2-H sensors can provide analogue interface (signal outputting from 0 to 10 V voltage with linear voltage dependence vary with measured level of fuel), when using FV-10 frequency-to-voltage converter.
