WORKING PRESSURE POINTER FOR ELECTRIC-CONTACT MANOMETRE Russian patent published in 2010 - IPC G01L19/08 

FIELD: physics.

SUBSTANCE: device which indicates working pressure of an electric-contact manometre consists of a radial guide with a guide channel, a holder which holds the radial guide on the housing of the electric-contact manometre and a rubber pointer. The radial guide serves for radial displacement of the pointer along the guide channel and is on the leading edge of the holder. The radial guide channel is made in form of a set of non-closed holes with smoothed mutual intersection mating. On the rear side of the radial guide there is a rear groove formed by a rear radial shoulder and the wall of the holder. The holder has the shape of a closed ring whose inner diametre is equal to the outer diametre of the housing. For rigid connection of the holder and the radial guide there are three reinforcing members. The pointer consists of an arrow, a neck and a cone. The neck of the pointer moves on holes in the radial channel. The cone with cut off chords is pressed in the rear groove. The pointer is fixed in the radial groove by passing the cone in the mounting opening at the beginning of the guide channel.

EFFECT: safe use of the device.
