FIELD: measuring.
SUBSTANCE: invention relates to the field of instrument making, in particular to devices for measuring the ratio of absolute pressures. Proposed device comprises inlet nozzle with diameter d1 connected with high-pressure feed channel, intake nozzle with diameter d2 connected with outlet channel, wherein the nozzles are coaxially installed in the body, and the inter-nozzle chamber is connected to the low pressure feed channel. Receiving nozzle opening has diameter d2 equal to d2=0.61*d1, and inlet part of receiving nozzle is made with rounded inlet edge with radius r=0.1*d1.
EFFECT: development of sensor less sensitive to abrasive dust wear, corresponding increase of sensor accuracy and reliability, increase of its service life.
