FIELD: measurement equipment.
SUBSTANCE: invention relates to pressure sensors used for measurement of process fluid medium and differential pressure. An assembly pressure sensor unit for pressure measurement of process fluid medium includes sensor housing with an available cavity formed in it, and the first and the second holes to the cavity, which are configured for application of the first and the second pressures. A membrane in the cavity separates the first hole from the second hole and is configured with a possibility of being bent in response to pressure difference between the first pressure and the second pressure. A provision is made for a capacity-type strain sensor configured with a possibility of determining the strain value of the sensor housing in response to line pressure applied to the sensor housing.
EFFECT: improvement of pressure measurement accuracy.
