Fuel level sensors
Epsilon ES2
Sensor of capacity type «Epsilon» is used with the purpose of precision measuring of level of filling the fuel of tanks of motor transport with an error, not exceeding 1%.This sensor is set in the checking systems after priming, weathering and expense of fuel in totality with the systems of satellite GPS/GLONASS monitoring of transport vehicles.
Advantages of «Epsilon» in relation to other sensors consist in
- to the simple facilitated construction weighing to 250 g
- possibilities of setting in flat reservoirs in a to 30 cm depth due to application of short measuring probes
- to very tall exactness of measuring of level of fuel, that is arrived at due to the increase of permission of sensor and linearness of measuring scale
- moduleness of execution, allowing to replace a measuring head regardless of probe, not coming running here to repeated calibration test reservoir
