Description
Digital Sensors with Serial Interfaces
The Evikon E2700 series of level sensors with digital interfaces is specially designed for high-precision measurement of fuel levels in automotive and stationary tanks. Applications include active driving systems, vehicle tracking, and control. Stability, accuracy, and reliability of measurements are achieved through the high precision of capacitive measurement technology with digital signal processing and the robust construction of the sensor.
High Accuracy and Linearity
The sensor resolution is less than 0.1% of the measurement scale, in most cases 0.07 mm. This ensures high measurement accuracy even in flat tanks. Thanks to two adjustable digital integrating filters, short-term fluctuations in fuel level do not affect the sensor readings. The built-in 32-point calibration system ensures a high degree of linearity in readings in user-selectable volume measurement units.
Reliable Construction
The E2700 series sensors are designed to provide maximum reliability and optimal operating characteristics. The sensor rod is made of a special lightweight alloy characterized by high strength and corrosion resistance. A vertical slot in the rod prevents clogging with fuel residues, facilitates cleaning, and reduces response time compared to rods shaped as closed tubes. The sensor electronics are hermetically sealed and fully protected from mechanical damage and corrosion.
Adjustable Rod Length
The sensor rod can be shortened on-site by up to 20% of its original length to match the tank depth. Rods of two standard lengths fit most fuel tanks: 800 mm, which can be shortened to 150 mm, and 1600 mm, which can be shortened to 300 mm. The maximum possible rod length is 2400 mm.
