1100 Series Diaphragm Type Differential Pressure Gauges

Key Features

  • Precisely measures pressure drops across filters, strainers, separators, heat exchangers and applications where a higher level of solids are present in the measuring media
  • High side is completely isolated from low side to prevent fluid movement between ports
  • Maximum static or working pressure to 3,000 psi; 1,500 psi with brass housing
  • 2-1/2" and 4-1/2" sizes – top & bottom, or back connected
  • Sensor housing is cast in a black anodized aluminum, 316L stainless steel or brass and comes standard with a weather-resistant NEMA 4X enclosure and shatter-resistant acrylic lens
  • Optional liquid filling lubricates gauge internals and extends service life by dampening the effects of vibration, pulsation and shock
  • Convoluted diaphragm fully supported to the rated working pressure of the gauge
  • Shipped with a certificate of calibration to ensure accuracy and quality performance
