The T/LL312 series of advanced sensors is designed to continuously monitor the contents of a tank in extreme temperature applications such as defence and off-highway vehicles. Capable of operating at temperatures between -40°C and +125°C, the sensor auto compensates when a liquid with a different dielectric constant is used. For example, if it is used in a tank of conventional diesel, the user can refill with bio-diesel and the sensor will correct the output level automatically.
Options include compensation for non-linear shaped tanks.
Diesel, biodiesel, kerosene, petrol, water or any liquid which is compatible
with the materials of construction.
