Wika Bourdon tube pressure gauge

Stainless Steel Series

Applications

  • With liquid-filled case for applications with high dynamic pressure pulsations or vibration
  • Suitable for corrosive environments and gaseous or liquid media that will not obstruct the pressure system
  • Process industry: chemical/petrochemical, power stations, mining, on and offshore, environmental technology, mechanical engineering and plant construction

Special Features

  • Excellent load-cycle stability and shock resistance
  • All stainless steel construction
  • Positive pressure ranges to 20,000 psi (1600 bar)
