Fuel sensor of the DPS14VT-4T

Each group of sensors has its own measuring (MIE) and compensating (MIT) bridges, which is caused by the need to have at each time the data on the fuel reserve in each group of tanks and the total fuel reserve on the aircraft.

The automatic part of SPUT4-I is designed to provide automatic control of fuel transfer, electro-hydraulic refueling valves and for signaling about an emergency fuel residue in the tanks. The measuring part of the SPUT4-I provides the sensors DTZSOB, DTSI4V and DTSK6V.
