POINTER PRESSURE GAUGE WITH INDUCTIVE SENSORS Russian patent published in 2012 - IPC G01L7/04 

FIELD: physics.

SUBSTANCE: pressure gauge has a housing inside of which there is an elastic sensitive element with a displacement mechanism for circular motion of the pointer with a blind and inductive sensors of limiting pressure values. The blind is made from component sheets lying one on top of the other, on which there are guides through which the sheets engage each other. When pressure changes to the maximum value, the sheets of the blind move apart in form of a fan to the angular range of 270 degrees for triggering the inductive sensors, and when returning to the zero value, the sheets of the blind come together and the blind takes the form of one sheet.

EFFECT: simple design of the pressure gauge.
