WIKA Differential Pressure Gauge (732.14, 762.14)

For the process industry, all-metal media chamber


  • For gaseous and liquid aggressive media that are not highly viscous or crystallising, also in aggressive environments
  • Pump monitoring and control
  • Filter monitoring
  • Level measurement on closed vessels

Special Features

  • Differential pressure measuring ranges from -1 … +30 bar [-14.5 … 435 psi] to 0 … 40 bar [0 … 580 psi]
  • High working pressure (static pressure) and high overload safety, selectable 40 bar [580 psi], 100 bar [1,450 psi], 250 bar [3,625 psi], 400 bar [5,800 psi] and 650 bar [9,425 psi]
  • The transmission fluid in the measuring chamber dampens the indicator in case of high changes of the rate of pressure
  • Model 73x.14: Stainless steel version
  • Model 76x.14: Version with special materials

These differential pressure gauges are made of highly corrosion-resistant stainless steel. A high overload safety is achieved by the all-metal construction and the close-fitting design of the diaphragm measuring element.

The use of high-quality stainless steel materials and the robust design are geared to applications in the chemical and process engineering industries. Thus the instrument is suitable for liquid and gaseous media, also in aggressive environments.

The wetted parts for these instruments are also available in special materials such as Monel or Hastelloy.

Scale ranges of 0 … 60 mbar to 0 … 40 bar [0 … 0.87 to 0 … 580 psi] ensure the measuring ranges required for a wide variety of applications.
