Details

The capacitive fuel level sensor ESCORT TD-BLE (hereinafter - the ‘Sensor’, ‘Device’ or “TD-BLE”) is designed to measure the level of light petroleum derivatives in the tanks of vehicles, machinery units and storage tanks.
The Device converts the fuel level readings into digital code. The Sensor transmits the level readings via Bluetooth (LE) channel in accordance with the ESCORT BLE protocol.
The Device has an autonomous power supply which is a replaceable lithium thionyl chloride non-rechargeable battery that does not require any maintenance. Applicable in explosive zones of 0, 1 and 2 (IEC 60079-10-1-2011) classes IIA JIB 31610-10-1-2022 as per explosion proof mark.
