LLS-D (Digital)
Fuel Level Sensors
CAP LLS-D Digital Fuel Level Sensor
Fuel level sensors use capacitive technology to accurately sense the fuel level in any tank type. No moving parts or floats. New mathematical filtration CAP technology.
This type of sensors also are ideal for use in harsh environments, where the temperature and vibration extremes make other types of sensors unsuitable.
CAP LLS-D Digital Fuel Level Sensor - with special CAP software fuel level sensors can be used for consumption/fueling/steeling control.
Special fuel level sensor with digital communication interface RS232/RS485/SAE J1939 designed for the fuel measurement system.
CAP LLS-D Digital Fuel Level Sensor can be installed in any type of motor vehicles, tractors, construction and agricultural machines, stationary fuel storage or diesel-electric locomotives.

CAP fuel level sensors now have new feature. Our sensors are completed with plastic plug: special fitting which permits to cut it to any necessary height to fit the fuel tank perfectly. In addition, plastic plug protects LLS from water, mud, and dirt that accumulates on the fuel tank bottom, and allows to avoid short circuit. |
