Applications
Stainless steel pressure gauges are widely used in industries such as petroleum, chemical, chemical fiber, metallurgy, power plants, mining, smelting, medical care, and food processing. They are suitable for various processes with high requirements for corrosion resistance and vibration resistance, to measure the pressure of different fluid media.

FAQ
Q1: What does seismic pressure gauge mean?
A1: These gauges are filled with a damping fluid (usually silicone oil or glycerin) to cushion the internal mechanism against mechanical vibrations and pressure pulsations. If your machine (e.g., a hydraulic pump or compressor) vibrates during operation, the seismic pressure gauge is essential to prevent pointer jitter and internal damage.
Q2: Is the seismic pressure gauge casing rust-proof?
A2: Yes, the casing is made of stainless steel, providing excellent corrosion resistance. Note: The connector (thread part) is made of copper, so it should not be used with media corrosive to copper (like ammonia).
Q3: Why is there an air bubble inside my stainless steel pressure gauge?
A3: This is normal. A small air bubble is necessary to allow for the thermal expansion and contraction of the damping oil. It does not affect the performance or accuracy of the gauge.
