      1131 Differential Pressure Gauge

      Overview

      The Ashcroft® 1131 differential pressure gauge is an economical means for measuring pressure between two independent pressure sources. Uses a rolling diaphragm design to separate high and low pressure ports and isolates media between low and high pressure sides.

      Key Features:

      • High static pressure capability (up to 200 bar)
      • Superior magnets for smoother pointer motion
      • Reed switches (optional) for direct system control

      Specifications:

      • Accuracy: ±2% (ascending pressure)
      • Pressure Ranges: 0 ... 250 mbar to 0 ... 7 bar
      • Dial size: 2 1/2", 3 1/2", 4", 4 1/2" and 6"
      • Case: stainless steel
      • Body: aluminum, brass or stainless steel
      • Wetted Material: body material, Teflon®, ceramic and various o-ring materials

      Applications

      The 1131 differential gauge is ideal where safe and reliable pressure measurement is essential:

      • Filtration Monitoring
      • Flow Measurement
      • Leak Detection
      • Clean Room Positive Pressure (low dp)
