Axial Glycerin Manometer: When to Choose It and What Problems It Solves in the Workshop

Is your workshop pressure gauge stuck and can't orders wait? Discover the axial glycerin pressure gauge options available at Tehnovest here!

You set the pressure to 6 bar, but the needle trembles and the result varies from one piece to another. In the workshop, pressure instability means repeated adjustments and inconsistent finishes. A glycerin-filled axial pressure gauge stabilizes the indication, maintains the setting, and gives you control in your operations.

What makes a glycerin pressure gauge different?

The difference from a dry pressure gauge is internal damping.

Glycerin fills the casing and increases the inertia of the needle. Vibrations produced by the compressor or airflow are absorbed, and the indication becomes stable. In the absence of liquid, the needle oscillates rapidly, and the internal mechanism wears out faster.

Concrete effect in the workshop:

Stable pressure at staplers = uniform penetration.

Constant pressure at spray guns = lacquer layer without differences in appearance.

Correct pressure at pneumatic wrenches = uniform tightening.

How to choose the accuracy class: 2.5, 1.6 or 1.0?

Class 2.5 general applications: Pressure adjustment at pneumatic staplers for sofa frames, air supply to blow guns or pneumatic wrenches used occasionally in the workshop.

Class 1.6 = finer control: Setting pressure on a lacquer spray gun where small differences change the texture or thickness of the applied layer.

Class 1.0 = processes with strict tolerances: Monitoring pressure on an automated industrial line or on the main compressor where deviations directly influence production parameters.

The class indicates the maximum allowable deviation reported to the measurement range. If your process reacts visibly to variations below 0.5 bar, class 1.6 or 1.0 becomes justified.

Axial or radial?

Choose axial when you want direct mounting on the installation or regulator. The connection is at the back, and the pressure gauge is fixed compactly on the equipment. For a local regulator on the workbench, an axial model Ø63 mm provides clear reading and takes up little space.
