product overview

The shock resistant pressure gauge consists of a pressure guiding system (including joints, spring tubes, flow limiting screws, etc.), a gear transmission mechanism, a reading device (pointer and dial), and a housing (including case, cover, glass, etc.). The outer shell is of an airtight structure, which can effectively protect the internal components from environmental influences and contamination invasion. The shock resistant pressure gauge is filled with damping fluid (usually silicone oil or glycerin) inside the housing, so it is also known asOil filled shock resistant pressure gaugeIt can resist working environment vibrations and reduce the pulsating effects of medium pressure. The shock resistant pressure gauge is suitable for places with severe environmental vibrations, and can withstand the pulsation, impact, and sudden unloading of the medium. The instrument indication is stable and clear, and it is widely used in mechanical, petroleum, chemical, metallurgical, mining, power and other departments.

Installation precautions

1. The ambient temperature for instrument use is -40~70 ℃, and the relative humidity is not greater than 80%. If it deviates from the normal operating temperature by 20 ℃, it must be included in the temperature additional error.
2. The instrument must be installed vertically, striving to be at the same level as the measuring point. If the difference is too high, it will be included in the additional error caused by the liquid column, which does not need to be considered when measuring gas. Block the explosion-proof port at the back of the watch case during installation to avoid affecting the explosion-proof performance.
3. The normal measurement range of the instrument should not exceed 3/4 of the upper measurement limit under static pressure and 2/3 of the upper measurement limit under fluctuation. Under the above two pressure conditions, the minimum measurement of the large pressure gauge should not be lower than 1/3 of the lower limit, and all vacuum parts should be used when measuring vacuum.
4. If the instrument pointer malfunctions or the internal components become loose or cannot work properly during use, maintenance should be carried out or the manufacturer should be contacted for repair.
5. Instruments should avoid vibration and collision to prevent damage.
6. Please indicate the instrument model and name when placing an order; The measurement range of the instrument; The accuracy level of the instrument deviates from the packaging requirements and others.
7. Special design based on user requirements.
