Ashcroft Pressure Gauge Type 1131

The Ashcroft® type 1130 Differential Pressure Gauge is an economical means for measuring pressure between two independent pressure sources. Used on process monitoring or control, the unit's system design permits a small volume of media migration; intended for air, hydraulic oil and non-corrosive applications. A good choice for satisfying challenging pressure requirements

Differential Pressure Gauge - ±2% Ascending Accuracy

  • Rolling diaphragm actuator
  • Stainless steel case
  • Ranges from 5 psid-100 psid
  • Static pressures up to 3000 psi
  • Aluminum (3), brass or stainless steel bodies (1)
  • Buna-N O-rings (others available)

The Type 1131 is utilized for applications where migration of the process media is not permissible. The Type 1131 uses a rolling diaphragm design to separate the high and low-pressure ports to isolate the media and can see up to 3000 psi static pressures. Body materials are available in Aluminum, Brass and Stainless Steel, with Buna, Viton or EPDM seals. (2)
