Pressure Gauge WIKA Model PG23CP


The high-quality model PG23CP pressure gauge has been designed especially for the requirements of the process industry. This safety pressure gauge is mainly used for applications in the chemical and petrochemical indusrty, the oil and gas industry, power engineering and also in water/wastewater technology.

Typical measuring points are on control units and control panels such as hydraulic power units (HPUs). For secure mounting of the instrument, a high-quality front bezel is used. The mounting situations mainly require an IP66 ingress protection. For this reason, the sealing of the model PG23CP to the panel is made using an all welded mounting ring and a mattched flat gasket.

Pressure gauges for the process industry are manufactured completely from stainless steel for increased corrosion resistance. This enables use in the measurement of aggressive gaseous or liquid media, also in aggressive environments. In the EN 837-1 standard for pressure gauges, safety versions are defined. For most applications, a safety version is not required.


  • For gaseous and liquid aggressive media that are not highly viscous or crystallising, also in aggressive environments
  • Specifically for the requirements within the process industry, mainly in the chemical and petrochemical industry, the oil and gas industry, power engineering and also in water/wastewater technology
  • Particulary suitable for use in welhead control panels (WHCPs) and hydraulic power units.


  • All welded mounting ring to avoid ingress of water into the panel (ingress protection IP6)
  • All stainless steel construction
  • Optionally as safety version “S3” per EN 837-1
