The YBN Series Seismic-resistant Stainless Steel Pressure Gauge is a stainless steel pressure gauge with liquid-filled vibration-resistant construction. It is mainly used for pressure detection where the measured pressure has strong pulsation, pressure shock or the site has significant vibration.
The gauge measures the average value of gas or liquid pulsating pressure and helps reduce damage caused by strong pulsation and vibration, improving reading stability and accuracy.
- Pressure detection in metallurgy, electric power, petroleum, chemical, light industry and machinery.
- Pressure measurement with strong pulsation or pressure shock.
- Production processes with frequent sudden unloading.
- Sites with significant environmental vibration.
- Gas and liquid pulsating pressure measurement.
- Vibration-resistant construction: Liquid filling and damping measures improve seismic performance.
- Stainless steel material options: Shell and wetted material are available as 304SS or 316SS.
- Selectable fill fluids: Silicone oil and glycerol are available according to operating temperature.
- Multiple protection ratings: IP55, IP65 and IP66 are available.
- Flexible mounting and accessories: Common mounting forms and pressure gauge accessories can be selected.
The gauge uses damping oil and buffering measures inside the case to improve vibration resistance. It is suitable for pressure measurement with strong pulsation or shock and for environments with significant vibration. The instrument indicates the average value of gas or liquid pulsating pressure.
