LLS-Ex 5

Explosion-Proof Fuel Level Sensor

The Omnicomm LLS-Ex 5 digital fuel level sensor is designed for use in potentially hazardous zones requiring explosion-proof equipment. This sensor is perfect for measuring fuel levels in fuel tankers and stationary fuel storage facilities operating in compliance with international safety standards. LLS-Ex 5 is ATEX-certified, confirming its suitability for explosion-hazardous environments.

Important: The LLS-Ex 5 sensor must be installed and connected to GPS-trackers exclusively via the Spark protection unit Omnicomm BIS-MX. This ensures compliance with explosion protection requirements and guarantees the safe and reliable operation of the system.
