DEVICE FOR DETERMINING PRESSURE OF SOFT TANK FOR WATER, DEVICE FOR CONTROLLING INLET OF SOFT TANK FOR WATER AND WATER PURIFIER WITH SOFT TANK FOR WATER Russian patent published in 2018 - IPC G01L9/00 G01L19/00 

FIELD: measuring equipment.

SUBSTANCE: invention relates to device (100) for determining the pressure of a soft water tank, device (1000) for controlling the inlet of the soft water tank and a water purifier with a soft water tank. Device (100) for determining the pressure of the soft water tank includes base (10), forming airtight cavity (101) inside it, the upper end of which has an installation hole, pressure sensor module (20), at least the lower part of which is located in airtight cavity (101) and is connected to the circumferential edge of the installation hole in a hermetic manner, while inductive head (22) of the module of the pressure sensor is made with the ability to abut the lower part of the soft water tank, and vent element (30), forming vent duct (301) inside and arranged on the base, vent duct (301) has balancing sealing element (40), which is adapted to move in vent duct (301) depending on changes in the pressure in airtight cavity (101) and in ambient pressure.

EFFECT: increased measurement accuracy and safety.
