In the field of industrial pressure monitoring, Oil Filled Pressure Gauges (oil filled pressure gauges) have become the core choice for complex working conditions due to their excellent durability and measurement accuracy. The product is injected with high-purity glycerin or silicone oil in a solid sealed housing. Through the physical damping characteristics of the liquid, it effectively absorbs mechanical vibration and pressure pulses to ensure smooth and clear pointer readings. Its basic structure includes a high-precision Bourdon tube (Bourdon Tube), an all-stainless steel shell and an internal movement with self-lubricating function, which reduces the friction loss between moving parts from the source and greatly extends the service life of the equipment in harsh environments. This series of products show strong environmental adaptability and economic benefits. The fully sealed design not only prevents internal condensation and freezing, but also maintains high accuracy of ± 1.0% to ± 1.6% in highly humid or corrosive chemical environments. Diversified material configuration (such as 316L stainless steel or Hastelloy) and a variety of installation forms (radial, axial, belt edge installation, etc.), so that it is widely used in petrochemical, hydraulic power, food and pharmaceutical and water treatment industries. This structural advantage significantly reduces the maintenance frequency and replacement cost of the enterprise, and is an ideal choice for achieving stable control of industrial processes.

Double hydraulic damping technology
the internal filling of high-viscosity glycerin can absorb up to 90% of the external vibration and system pressure pulse, completely eliminate the sharp shaking of the pointer, and ensure that the reading deviation is controlled within ± 0.2 under severe vibration environment.

Fully sealed anti-condensation design
IP65 industrial sealing standard is adopted to effectively block air humidity and prevent fog or frost from being generated inside the window. Even in extreme weather of -40 ℃ or salt spray environment with high humidity, the vision remains clear.

Self-lubricating movement to extend life
the filling fluid acts as a permanent lubricant, so that the gear transmission mechanism between the friction coefficient is reduced by more than 50%, effectively prevent the mechanical failure caused by dry grinding, so that the average service life of the product is extended by 3-5 years than the ordinary dry meter.

Internal pressure automatic compensation system
the top is equipped with a special vent plug or flexible sealing window, which can automatically adjust the pressure balance inside and outside the case according to the change of the external environment pressure, so as to ensure the highest level of measurement accuracy in low pressure measurement occasions (such as vacuum measurement).

316L stainless steel anti-corrosion and compression
medical grade 316L stainless steel is selected for liquid receiving parts, which has excellent chemical stability and can withstand corrosion of high concentration acid and alkali media. Its structural strength supports instantaneous overpressure protection up to 130% of full scale without damage.

Wide-area temperature compensation mechanism
silicone oil filling version is provided for different industry requirements, which can maintain stable viscosity in a wide temperature range of -60 ℃ to 200 ℃, avoid indication drift caused by large fluctuations in ambient temperature, and meet the requirements of aerospace-level working conditions.
