FIELD: control and measuring equipment.
SUBSTANCE: invention can be used in gas turbine engine control systems. Absolute pressure ratio jet sensor, comprising a feed nozzle with an oblique cut, the input of which is connected to a high pressure source PP, and output is connected to interaction chamber connected to low pressure source PL, two receiving channels located opposite the feed nozzle in the same plane with it and at an angle relative to its axis, characterized by that the output part of the feed nozzle is made convergent.
EFFECT: possibility of creating a sensor, in which zero pressure difference in receiving channels is formed at low pressure ratio PP/PL≤2.5.
