Pressure Gauge Model 232.30

DESCRIPTION

This high-quality Bourdon tube pressure gauge has been designed especially for increased safety requirements within the process industry

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

Scale ranges 0….0.6 to 0…1,600 bar the measuring ranges required for a wide variety of applications.

WIKA manufactures and qualifies the pressure gauge in accordance with the requirements of the EN 837-1

European Standard in the”S3″ safety version. The safety version is made up of a non-splintering window, a

solid baffle wall between measuring system and dial and a blow-out back. In the event of failure, the

operator is protected at the front side, as media or coponents can only be ejected via back of the case.

For harsh operating conditions, all instruments are also available with an optional liquid filling.

 

APPLICATION

  • Increased safety requirements for personal protection
  • With liquid-filled case for application with high dynamic pressure loads or vibration (model 233.30)
  • For gaseous and liquis aggressive media that are not highly viscous or crystallising, also in aggrssive environments.
  • Oil and gas industry, chemical and petrochemical industries, power engineering and also water and wastewater technology.

SPECIAL FEATURES

  • Sfaety version with soli baffle wall designed in compliance with the requirements and test conditions of EN 837-1
  • Excellent load-cycle stability and shoc resistance
  • Completely from stainless steel
  • Scale ranges from 0…0.6 to 0…1,600 bar
