Type 1490 Low Pressure Diaphragm Gauge, ASME B 40.1 Grade A (±2-1-2% of span)

 

  • 2.5" and 3.5" dial size
  • Glass-filled polysulfone case material, won't rust or dent
  • Beryllium  copper diaphragm
  • Brass socket
  • Wetted materials of beryllium copper, brass, polysulfone and RTV silicone
  • Exclusive autoclavable feature
    The Ashcroft® Type 1490 low pressure diaphragm gauge is designed to measure pressure from 10 in.H2O to 15 psi, both positive and negative pressures.  This gauge uses a very sensitive diaphragm capsule to measure low pressure and vacuum.  The gauge is specifically designed for use whenever the pressure medium is a gas that is not corrosive to beryllium copper, brass, polysulfone and RTV silicone.  The polysulfone case is suitable for intermittent or continuous service on natural gas provided a .013" throttle plug is installed in the socket.  Typical applications are, but not limited to, vacuum pumps, gas leak detectors, air compressors, air filters, gas burners, gas measurement, vacuum ovens, suction regulators and respirators.
