FIELD: measuring engineering.
SUBSTANCE: device comprises pressure chamber (11) defined between base (1) and separating diaphragm (2). The pressure chamber can be filled with the second fluid and provided with port (12) through which pressure can be transmitted by means of the second fluid to the cell for measuring pressure. The device has pickup for permanent control of the properties of mater that composes the second fluid, conductivity pickup that has at least one electrode (31), (32) which can be sensitive to the contamination of the second fluid by the first one due to the distortion of separating diaphragm (2) caused by changing controllable property of matter. The pickup is in communication with pressure chamber (11) through port (12) made in the pressure chamber.
EFFECT: accelerated operation.
