WIKA Model 231.11 Precision Digital Pressure Gauges

For HP (high purity) applications


  • For plants and equipment where measured values must be read from a distance
  • Suitable for gaseous or liquid media that will not obstruct the pressure system
  • Referred to as "Boiler Gauge" in the industry

Product Features

  • Measuring ranges up to 0 ... 10,000 bar (0 ... 150,000 psi), vacuum and absolute pressure ranges also available
  • Accuracy: up to 0.025 % (incl. calibration certificate)
  • Intrinsically safe version
  • Logger function with up to 50 measured values per second
  • Communication with WIKA-Cal software over WIKA-Wireless


    • Design
      ASME B40.100 & EN 837-1


    • Sizes
      10" (250 mm)


    • Accuracy Class
      � 1% of span (ASME B40.100 Grade 1A)


    • Ranges
      Vacuum / Compound to 200 psi (16 bar)
      Pressure from 15 psi (1 bar) to 15,000 psi (1000 bar) or other equivalent units of pressure or vacuum


    • Working Pressure
      Steady: full scale value
      Fluctuating: 0.9 x full scale value
      Short time: 1.3 x full scale value


    • Operating Temperature
      Ambient: -40°F to +140°F (-40°C to +60°C)
      Medium: max. +180°F (+80°C) - Type 211.11
      max. +392°F (+200°C) - Type 231.11


    • Temperature Error
      Additional error when temperature changes from reference temperature of 68°F (20°C) �0.4% of span for every 18°F (10°K) rising or falling.


    • Sampling rate
      The measuring rate can be user-defined to match the type of measurement required. Standard applications usually use three measured values per second. If required, this rate can also be set to 50 measured values per second. Via an energy-saving function, the CPG1500 switches automatically into "sleep" mode, in this mode the battery life can be increased up to 2,500 hours.


  • Features
    Through the new and innovative menu navigation, simple operation is ensured. The clear display, with integral bar graph display and large text area, assists with the effective analysis of the widest variety of measuring points. With the MIN/MAX function, the highest and lowest pressures can be accessed immediately and saved automatically.
