Omnicomm LLS fuel- level sensors

Omnicomm’s capacitive sensors have a long work-life and require no technical maintenance. Delivering exceptionally high accuracy levels of 99.2% and consistent reliability, even in extreme temperature variations, Omnicomm sensors have a wide application area and can be fitted to the fuel tanks of virtually any vehicle – on land and on sea, across multiple industries.

Omnicomm’s sensors include the LLS 4, the LLS-AF 4, the explosion-proof LLS 20230 and the LLS heavy-duty sensor. They are robust and precise, delivering consistently high accuracy in even the most testing conditions.
THE OMNICOMM LLS 4: UNPRECEDENTED ACCURACY & RELIABILITY
THE OMNICOMM LLS 4: UNPRECEDENTED ACCURACY & RELIABILITY

The Omnicomm LLS 4 provides unprecedented accuracy and reliability. It’s extremely tough, with increased all-round protection, including against electrostatic, electromagnetic and conducted interference. The sensor head is shock resistant while its neat size facilitates installation even in units with limited space between the fuel tank and other vehicle parts. The LLS 4 has an ingress protection rating of IP-69K.

THE OMNICOMM LLS-AF 4: ULTIMATE STRENGTH & STABILITY
THE OMNICOMM LLS-AF 4: ULTIMATE STRENGTH & STABILITY

The Omnicomm LLS-AF 4 features an adjustable analog output for extra stability, so the output voltage doesn’t rely on the supply voltage. Frequency output provides a frequency-modulated pulse signal. Both analog and frequency outputs are protected against short circuiting, reverse polarity and voltage supply. The cable connection slot with over-moulding is ultra-resistant to humidity and the LLS-AF 4 also has an ingress protection rating of IP-69K.
