MANOMETRE WITH LIMITING VALUE SENSOR Russian patent published in 2010 - IPC G01L7/00 

FIELD: physics.

SUBSTANCE: manometre has a cylindrical housing inside of which there is a holder which ends with a socket piece for connection to the measured pressure from outside the housing, a Bourdon spring and a protective transparent glass which is disc shaped and is placed over a dial plate with a scale and a pointer on which there is a shutter. The shutter is made from opaque material in form of a thin-walled hollow cylinder, the lower base of which is made from a thin-walled circular plate and which lies perpendicularly. The diametre of the hollow cylinder of the shutter is lies along the medial line of the pointer. The pressure limiting value sensor is mounted on the pressure limiting value pointer which is placed over the shutter and mounted on an axle resting on the cantilever span of an L-shaped arm in line with the pinion axis, and constructively has limitations in establishing angle values of up to 180°. The base of the arm is fixed using two screws on the face of the dial plate.

EFFECT: wider range of operation of the sensor mounted on the pointer of limiting pressure values.
