PRODUCT DESCRIPTION

Main Material	Stainless Steel
Product Features	The pressure gauge is filled with damping liquid (usually glycerin for temperatures between 5-55°C, or silicone oil for temperatures between 25-55°C). This design helps resist vibrations in the operating environment and reduces the impact of pressure pulsations in the medium. It is compact, safe, reliable, and has excellent shock resistance.
Testing Method	The testing process complies with the standard GB/T 1227-2002 “Precision Pressure Gauges.”
Factory Testing	100%

The shock-resistant pressure gauge is designed for use in environments with severe vibrations. It can withstand medium pulsation, shock, and sudden unloading. The gauge provides stable and clear readings.

It is widely used in industries such as machinery, petroleum, chemicals, metallurgy, mining, and power generation, where it is used to measure the pressure of non-corrosive media to copper and copper alloys.

Standards:

Instrument Standard: JB/T6804-93
Working Temperature: -25°C to 70°C (with liquid-filled case)
Vibration Frequency: Maximum 25Hz; Amplitude ≤ 1mm
Temperature Effect: ≤ 0.4%/10°C (at a reference temperature of 20±5°C)
Vibration Resistance: V, H, and Level 4 (with liquid-filled case)

Usage and Ordering Notes:

If the instrument does not return to zero due to high environmental temperature, a small hole can be made in the rubber plug of the instrument using a fine needle, allowing the internal chamber to vent to the atmosphere.
The operating environment should be free from corrosive gases.
When placing an order, please specify the name, model, and measurement range.
