Glycerin pressure gauge

OPG Series

·         Movement of the pointer due to mechanical vibration is absorbed by the viscous drag of the glycerin liquid in the hermetically-sealed pressure gauge. Movement of the Bourdon tube is also absorbed, thereby absorbing the pulsating pressure of the fluid.

·         Glycerin liquid serves as lubricating oil for the friction part of the bearing and gear in the pressure gauge, thereby ensuring durability of the internal mechanism.

·         Safety measures are provided to ensure that the front glass is not thrown away and hydraulic oil is purged out of the safety valve, if the Bourdon tube be broken.

·         Since the green safety mark is attached to the circumference of the case, pressure range setting can be set easily (only for 60 mm-diameter type).

                  Select a pressure gauge whose top pressure reading is more than double the applicable pressure range.
