Product Introduction

Precision instrumentation engineered for anti vibration oil filled pressure gauge applications

The Anti Vibration Oil Filled Pressure Gauge targets a single, very common failure: gauges mounted on machinery that shakes and pulsates. Reciprocating pumps, diesel engines, hydraulic presses, and compressors create rapid pressure fluctuations and mechanical vibration that make a dry gauge's needle blur, wear out its gears, and drift from calibration in weeks. Here the whole movement runs in silicone or glycerin liquid, and the design is tuned for continuous shaking rather than occasional shocks.

Two features work together. First, a restrictor orifice or adjustable damping screw in the socket reduces the speed at which pressure pulses reach the Bourdon tube, so the tube responds to average pressure instead of every stroke. Second, a counterbalanced pointer and a lightweight, reinforced gear train reduce the inertia that would otherwise make the needle swing with vibration. The liquid fill adds viscous damping and lubrication to complete the picture.

Every gauge is assembled in our 100,000-level clean workshop and endurance tested on a vibration table and pulsation rig before release. Fill liquid grade, restrictor setting, vibration test data, and calibration results are stored in our Advanced MES digital tracking system against each serial number, so a plant can trace which damping configuration is installed at each point and reorder the same specification.

Different from a seismic gauge, which is built to survive a few violent shocks, this model is optimized for sustained vibration at engine and pump frequencies, and is offered with liquid viscosity options from light to heavy so damping can be matched to pulsation severity. Bottom, back, and panel-mount versions allow it to be fitted on skid frames and machine consoles.

Core Advantages

Engineered for reliability where it matters most

Restrictor

Adjustable Damping Screw

Counterbalanced

Low-Inertia Pointer

Multi-Viscosity

Fill Options for Pulsation Severity

Restrictor Screw Damping — Adjustable orifice limits the pulse energy reaching the Bourdon tube so it reads average pressure
Counterbalanced Pointer — Balanced needle and light gear train reduce inertia that would exaggerate vibration
Viscosity-Matched Fill — Choose light to heavy fill oil to fit the severity of pulsation and temperature
Vibration Table Endurance Tested — Units are shaken and pulsed on test rigs before release rather than only checked statically
Multiple Mounting Formats — Bottom, back, and panel-mount versions suit skid frames, consoles, and machine panels
MES Traced Production — Serial-linked quality data from raw material to shipment for full after-sale traceability

Industrial Applications

Where anti vibration oil filled pressure gauge performance is mission-critical

Reciprocating Pump Discharge Lines

Reads stable average pressure on piston and plunger pumps that create strong pulses

Diesel Engine and Generator Sets

Monitors oil and fuel pressure on engines with continuous vibration

Hydraulic Presses and Power Packs

Handles rapid pressure spikes and vibration on press hydraulics

Air Compressor Discharge

Provides stable reading on reciprocating compressor receivers and lines

Mobile Machinery and Agricultural Equipment

Technical Highlights & QC

Every unit validated for zero-defect performance

Vibration Table Endurance: Samples are run on a vibration table at machine frequencies to check for wear, zero drift, and fill leakage.
Pulsation Rig Testing: Gauges are connected to a pulsation generator to confirm needle steadiness and Bourdon tube durability.
Restrictor Setting Verification: Each restrictor is set and verified to give a controlled response time.
Pointer Balance Check: Pointer counterbalancing is inspected to confirm no imbalance that would cause vibration flutter.
Case Leak Test: Sealed cases are inspected under vibration to confirm no fill leakage.
MES Serial Tracking: Fill viscosity, restrictor setting, and calibration data are stored digitally against each unit's serial number.

Environment & Media Compatibility

Engineered for demanding operating environments

Continuous Machine Vibration: Fill, restrictor, and balanced pointer are tuned for sustained shaking rather than occasional shocks.
Reciprocating Pump Pulsation: Restrictor smooths pressure pulses from pumps that deliver in discrete strokes.
Engine Compartment Heat: Silicone fill viscosity remains stable at engine bay temperatures.
Outdoor Mobile Equipment: Sealed stainless case resists weather and dust on mobile machinery.
Hydraulic Oil Contact: Wetted parts and seals are compatible with mineral and synthetic hydraulic oils.
Rapid Pressure Spikes: Restrictor and Bourdon tube design protect the gauge from short spikes beyond normal range.

Pro Tips for Longevity

Installation & maintenance best practices

Start with Medium Damping: Begin with the standard restrictor setting and adjust only if the needle still flutters.
Do Not Over-Restrict: Excessive damping slows response and can hide real pressure changes.
Mount on a Stable Structure: Fix the gauge to a rigid bracket or panel rather than directly on a vibrating pipe.
Use a Flexible Line: A short flexible hose isolates the gauge from pipe vibration.
Match Fill to Temperature: Use higher-viscosity fill for high pulsation and moderate temperature; lighter fill for cold climates.
Inspect for Leakage Regularly: On vibrating machinery, check periodically for fill leakage or loose fittings.

Frequently Asked Questions

Everything you need to know before specifying or ordering

What is the difference between an anti-vibration and a seismic gauge?

Anti-vibration gauges are tuned for continuous machine vibration and pulsation, while seismic gauges are reinforced for a few violent shocks.

What does the restrictor screw do?

It limits how fast pressure pulses reach the Bourdon tube so the pointer follows average pressure.

Can I adjust the damping in the field?

Yes, the screw allows adjustment; start at the default setting and change only if needed.

Which fill liquid should I choose?

Higher viscosity for severe pulsation at moderate temperature, lower viscosity for cold climates.

Will damping hide real pressure changes?

Too much restriction slows response, so use the minimum needed to stabilize the needle.

Is a snubber still needed?

On very violent pulsation, a separate snubber may be added in addition to the restrictor.

Can it be used on hydraulic presses?

Yes, provided the range is chosen so the working pressure sits mid-scale and spikes remain below the maximum.

Does it work on diesel engines?

Yes, it is commonly used for oil and fuel pressure on engines with continuous vibration.

What accuracy is standard?

Class 1.6, with better classes available for specific ranges.

What mounting styles are offered?

Bottom, back, and panel-mount versions are available for skids and consoles.
