In industrial fields such as petroleum, chemical, synthetic fiber, metallurgy, and power plants, precise measurement of fluid medium pressure is the key to ensuring production safety and efficiency in processes that require high corrosion resistance and vibration resistance. Sanitary grade stainless steel oil filled shock resistant pressure gauges have become an ideal choice in these industries due to their performance. This article will provide a detailed introduction to the technical specifications, application scenarios, and installation precautions of the pressure gauge, providing comprehensive reference for engineering and technical personnel.

1、 Product Overview and Working Principle

Sanitary grade stainless steel oil filled shock resistant pressure gauge, specially designed for harsh working conditions, made of high-quality stainless steel material, with good corrosion resistance and mechanical strength. Its core components include the pressure guiding system (including joints, spring tubes, current limiting screws, etc.), gear transmission mechanism, indicating device (pointer and dial), and housing (case, cover, glass, etc.). Through the elastic deformation of stainless steel sensitive components (such as Bourdon tubes, bellows, and bellows) inside the watch, the pressure changes are transmitted to the pointer through the movement conversion mechanism, achieving intuitive display of pressure. Liquid filled design (usually silicone oil or glycerin) effectively resists working environment vibrations and reduces the impact of medium pressure pulsation on measurement accuracy.

3、 Product application

This pressure gauge is widely used in industrial sectors such as petroleum refining, chemical production, chemical fiber manufacturing, metallurgical processing, and power generation, especially in processes that require corrosion resistance, vibration resistance, and high measurement accuracy, such as reactor pressure monitoring, pipeline fluid pressure control, etc., playing an important role.

4、 Installation precautions

Selection of pressure measuring points:

It should be selected in the pipeline section where the measured medium flows in a straight line, avoiding bends, forks, dead corners, or areas prone to vortex formation.

When measuring the pressure of a flowing medium, the pressure measuring point should be perpendicular to the flow direction and any burrs in the borehole should be removed to reduce measurement errors.

When measuring liquid pressure, the pressure measuring point should be located at the lower part of the pipeline to prevent gas accumulation; When measuring gas pressure, it should be located above the pipeline to avoid liquid accumulation.

Environmental considerations: Ensure that the installation location is away from heat sources, corrosive substances, and strong electromagnetic fields to reduce the impact of external factors on measurement results.

Regular maintenance and calibration: Regularly check the sealing, pointer flexibility, and reading accuracy of the pressure gauge, and calibrate it if necessary to ensure long-term stable operation.
