2Inch 50MM Shockproof Pressure Gauge with Stainless Steel Case

• Product Description

Shock-resistant pressure gauges, also known as vibration-resistant pressure gauges, include stainless steel shock-resistant pressure gauges, shock-resistant electrical contact pressure gauges, diaphragm shock-resistant pressure gauges, axial shock-resistant pressure gauges, shock-resistant precision pressure gauges, and shock-resistant remote transmission pressure gauges. This series of instruments has excellent shock resistance and is particularly suitable for measuring the pressure of liquids, gases, or vapors that are non-explosive, non-crystallizing, non-solidifying, and non-corrosive to copper and copper alloys, under conditions of strong mechanical vibration and severe pressure pulsation. The instruments provide stable indication and clear readings. They are widely used in heavy machinery, mining, petroleum, chemical, metallurgical, and power industries.

The principle of a shock-resistant pressure gauge:

It consists of a pressure-conducting system (including connectors, Bourdon tubes, flow-limiting screws, etc.), a gear transmission mechanism, an indicating device (pointer and dial), and a housing (including the case, cover, and glass).

The shock-resistant pressure gauge housing is airtight, effectively protecting internal components from environmental influences and contaminant intrusion.

The shock-resistant pressure gauge is an instrument filled with damping fluid (usually silicone oil or glycerin) inside the housing, which helps it resist vibrations in the working environment and reduce the effects of pressure pulsations.

Technical parameters

Installation Notes

1. The instrument's operating ambient temperature is -40~70℃, and the relative humidity is no more than 80%. If the temperature deviates from the normal operating temperature by 20-5℃, an additional temperature error must be considered.

2. The instrument must be installed vertically, ideally level with the measurement point. If the difference is too large, an additional error caused by the liquid column must be considered; this is not necessary when measuring gases. Block the explosion-proof port at the rear of the casing during installation to avoid affecting the explosion-proof performance.

3. The normal operating measurement range of the instrument: under static pressure, it should not exceed 3/4 of the upper limit of the measurement range; under fluctuating pressure, it should not exceed 2/3 of the upper limit of the measurement range. Under both pressure conditions, the maximum pressure gauge measurement should not be lower than 1/3 of the lower limit. When measuring vacuum, the entire vacuum section should be used.

4. If the instrument pointer malfunctions, or internal parts become loose, or the instrument fails to operate normally, it should be inspected and repaired, or the manufacturer should be contacted for repair.

5. The instrument should be protected from vibration and impact to prevent damage. 6. When ordering, please specify: instrument model and name; instrument measurement range; accuracy class deviation from standard packaging requirements and other details.

7. Custom designs are available based on user requirements.

Applications

Vibration-resistant pressure gauges are suitable for environments with severe vibrations. They can withstand medium pulsation, impacts, and sudden unloading, and the instrument readings are stable and clear. They are widely used in machinery, petroleum, chemical, metallurgical, mining, and power industries to measure the pressure of media that are non-corrosive to copper and copper alloys.
