WEIGHT TYPE PRESSURE GAGE

摘要

PURPOSE:To allow a titled gage to easily respond to high and low pressures by providing a spacer sealed by a packing between a casing and a cylinder, and changing the size of this spacer. CONSTITUTION:The lower part of a ram 2 is inserted into the bore of a cylinder 1 freely slidably by having a prescribed clearance. A weight 3 is placed on the top part of this ram 2. The cylinder 1 is formed into a stepped cylindrical shape having a collar part in the upper part and a casing 5 is provided with a stepped recess for containing the cylinder 1. With a ringlike packing 9 and a ringlike spacer 1 held interposed between the collar part of the cylinder and the step part of the casing 5, the cylinder 1 is contained in the casing 5. It is possible to change the size H in the height direction of a clearance 7 by changing the size h in the height direction of the spacer 10, and to set the rate of deformation of the cylinder 1 according to the pressure P of a pressure medium to be measured.
