FIELD: physics. ^ SUBSTANCE: pressure gauge has a cylindrical housing, an elastic sensitive element with a mechanism for circular movement of the pointer with a blind and protective clear glass. The pointer with a semi-circular plate of indicator blind is integrated with a support arm and a balance beam. The support arm lies perpendicular to both the diameter D of the indicator blind and the chord L of the balance beam-counterweight. Induction sensors lie on pointers of limit pressure values at radii R1 and R2 from the axis of the tube. One induction sensor lies at a distance shorter than the radius R1 and the second induction sensor lies at a distance greater than the radius R2. The value of the radius R3 of the indicator blind is greater than the value of the larger radius R2 and during rotation of the indicator blind, induction sensors of limit pressure values are covered. In the first pointer of limit pressure values at a distance of the larger radius R2, there is a semi-circular cut into which the semi-circular protrusion of the second induction sensor enters when limit value pointers are superimposed. The limit value pointers structurally have a limit of 180 degrees in setting the range of separation of pointers. ^ EFFECT: simple design of the pressure gauge. ^ 2 cl, 3 dwg |
