1. Use
Fuel level sensor Epsilon (hereinafter referred to as the FLS or sensor) is used to measure the
fuel level in containers and fuel tanks (hereinafter - the tanks) of vehicles (hereinafter – the
vehicles).
The sensor can be used in conjunction with the equipment that supports a unified
communications protocol Epsilon Data Exchange (hereinafter - EDE) and (or) processing of the
analog signal.
The sensor is compatible with different control units, concentrators and equipment of GPS -
monitoring, such as follows:
Autograph
Ruptela
Dalcon
Pointer
Intellitrac
M2M Telematics
BCE
Teletrack
Teltonika… etc.
Model Epsilon ES2 provides data exchange on the interface RS-232, ES4 – on the interface
RS-485. The add-on device (digital to analog converter EG4x) ensures the formation of an
analog signal and exchange on the interface RS-485.
2. Explosion Protection
The sensor is explosion-protected and it has such explosion protection marking:
1Exm[ia]IICT6 Х - for use in Russian Federation.
1ExsiaIICT6 X - for use in Ukraine;
The sign "X" in the marking of explosion protection shows special conditions of safe use of
sensors as follows:
sensors should be connected to the electrical circuits of equipment that feeds only from the car
battery with voltage not more than 36 V and has no electrical connections with electrical
equipment that has other sources of supply, including the network ones;
connection of sensors to the mains supply should be carried out via a fuse rated at no more
than 0.1 A.
Documents confirming compliance of the sensor with the requirements of explosion protection:
Certificate of conformity of the Russian Federation State Standard № РОСС.UA.ME92.B02278
and certificate № 2703 of the State Testing and Certification Center of Explosion-Protected and
Mine Electrical Equipment (Donetsk, Ukraine).
