Stainless Steel Case Pressure Gauges
B132 series
Applications:
Used with the liquid and gas process media not corrosive, not crystallizing and not highly viscous. The glycerin / silicon oil filled type is especially used for measuring points subject to vibration and highly dynamic pressure load. Particularly used in hydraulics, compressors, general mechanical engineering, pumps, water treatment plants, etc.
