Osmotic pressure sensor for continuous measurements

摘要

The invention relates to osmotic pressure sensors and more particularly those which are intended to operate continuously. It includes a measuring chamber (1) on which the semipermeable membrane (2), which is mobile, is fixed. It moves by sliding over a fixed piece (3) to pass from a position A in which a regeneration of the reference solvent is carried out, to a position B in which the pressure measurement is carried out using a sensor (6). The invention may be used in all cases where it is necessary to measure an osmotic pressure. IMAGE
