Features

  • The movement of the pointer due to mechanical vibration is absorbed by the viscous drag of glycerin liquid in the fully sealed pressure gauge.
  • The movement of the Bourdon tube is attenuated by the viscous drag of glycerin liquid, absorbing pulsating pressure of the fluid.
  • The glycerin liquid serves as lubricant for the friction part of the bearings and gears in the pressure gauge, thereby ensuring durability of the internal mechanism.
  • Safety design that prevents the front glass from scattering, if the Bourdon tube should be broken, by purging water from the safety cap.
  • The safety mark is provided on the circumference of the case, facilitating the setting of the pressure range.
  • Select a pressure gauge whose full scale pressure is more than double the pressure range in service.

How to use the safety mark

Instruction for use

  • Some combinations of shape, size, and pressure range are not available. Please refer to the type table for making your selection.。
  • The glycerin pressure gauge should be mounted vertically; otherwise an indication error or leakage of glycerin liquid may occur.
  • We do not offer glycerin pressure gauge with a special hand-written graduation.
  • In the case where the maximum operating pressure is 1 MPa or less, cut off the safety cap as shown in the figure below.
  • Since the torque of the Bourdon tube in pressure gauges of 1MPa or less is small, the temperature change (internal pressure change) in the gauge case will affect the indication accuracy. By cutting the safety cap tip, the internal pressure is well balanced with the atmospheric pressure, thereby maintaining the accuracy. The glycerin pressure gauge of 1 MPa or less, with the safety cap tip cut off, shall be used with the cap facing upward.
