Product brief introduction: anti vibration pressure instrument widely used in petroleum, metallurgy, live power, light industry, medicine, food and communications in the field ( technology and equipment ) pressure measurement system for non corrosive liquid medium pressure.

Characteristic

The appearance of fine, protective force: instrument shell ( table cover and case) system using special austenitic stainless steel, both to trim or bayonet type (the Y-100A Series) structure to seal connection; joint and the case to special structure form and supported by high quality sealing ring for reliable sealing.

Stable performance, durable: manometric components with advanced technology and equipment are made, and through a special process, so that it has high strength and elasticity, and excellent fatigue resistance.

Strong adaptability, high safety: case observation window selection of high-strength engineering plastics, can adapt to the harsh environment (e.g. temperature, high humidity, vibration more acuteness etc.), or even because of his improper use ( medium temperature is high or produce instantaneous overvoltage phenomenon ), also not to lead to potential risk.

Diversity of type, complete specifications: this instrument can be used for variety and more complete specifications pressure (see technology parameter column ); the pressure measuring unit in addition to the" M p a" give priority to, also can be made into" p s I, kgf/cm2" or" bar" and other units or master, pay two units (generally in export oriented); joint thread size of the public and the British, American and other several kinds of, let the user choose.

Structural reliability, quality and cheap: the instrument in the structure on a unique design, inside and outside mao. In terms of quality by ISO9001system to control and assurance, but the price is only equivalent to an ordinary Vibration-proof pressure gauge.

Structure and principle

This instrument consists of pressure pilot system (including joint, spring pipe ), a gear transmission mechanism, indicator device ( including the pointer and dial ) and the shell ( including watchcase, table cover, sealing gasket sheet glass, etc. ). Shell type structure, can effectively protect the internal mechanism from environmental influences and dirty invasion. For the vibration resistant type instrument, is resistant to the work environment more drama of the vibration and the measured pressure fluctuation effect. Instrument of reasonable overall structural design, fine craft, it has good stability and high durability. The meter work principle and the general pressure gauges and vibration-proof pressure gauge the same.
