Glycerin filled pressure gauge ø60 OSG G1/4type (SUS-spec)

which is the most standard size, comes standard with a safety mark! The coloring of the color coding option can also be installed.
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.
A dedicated throttle for absorbing pulsating pressure and surge pressure is built into the pressure gauge socket.
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.
Select a pressure gauge whose top pressure reading is more than double the applicable pressure range.
We issue various certificates related to pressure gauges for a fee.

Mount the glycerin pressure gauge vertically. Depending on the mounting orientation other than vertical, the indication accuracy may be disturbed or the glycerin filled liquid may leak.
Glycerin-filled pressure gauges with a hand-written special dial cannot be manufactured.
Please refer to "Precautions when using 【Color-ring CR】" for handling color-ring CR.
If the maximum scale is 1 MPa or less, raise the green plug on the safety cap before use.
【Safety cap for low pressure】
Attached to the range of 1 MPa or less.


Plug closed.
Raise the plug.

For pressure gauges of 1 MPa or less, the torque of the Bourdon tube is weak, so temperature changes (internal pressure changes) inside the pressure gauge case affect the indication accuracy.
By pulling up on the green plug, the internal and atmospheric pressures are balanced and accuracy is maintained.
After releasing the internal pressure, always use the product with the safety cap facing upwards.
【Safety cap for high pressure】
Attached to the range of 1.6 MPa or more.

Models with a range of 1.6 MPa or higher do not need to release the internal pressure.
