Pressure Gauge WIKA Model 232.34


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

By using stainless steel materials for the wtted parts and also a highly resistant plastic for the case, the model 232.34 achieves excellent corrosion resistance. With this, the instrument is ideal for liquid and gaseous media, even in aggressive environments.

Scale ranges of 0…0.6 bar to 0…1,000 bar ensure the measuring ranges required for a wide variety of applications

WIKA manufactures and qualifies the model 232.34 in accordance with the requirements of the American standard ASME B 40.100 in the safety version.

The safety version is made up of a non-splintering plastic 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 components can only be ejected via the back of the case.

For harsh operating condition, all instrument are also available with an optional case filling.


  • Increased safety requirements to protect the operator
  • With case filling for applications with high dynamic pressure loads and vibrations
  • For gaseous and liquid aggressive media that are not highly viscous or crystallising
  • Process industry : Chemical industry, petrochemical industry, power plants, mining, on-/offshore, environmental technology, machine building and general plant construction.


  • Features version with solid baffle wall designed in compliance with the requirements and test conditions of ASME B 40.100
  • Excellent load-cycle stability and shock resistance
  • Scale ranges from 0…0.6 to 0…1,000 bar



Per ASME B 40.100

Nominal size

4 ½”

Accuracy class

Grade 2A per ASME B 40.100 (corresponds to indication accuracy ±0.5 %)

Scale ranges

0 … 0.6 bar to 0 … 1,000 bar (0 … 10 psi to 0 … 15,000 psi)

or all other equivalent vacuum or combined pressure and vacuum ranges

Pressure limitation

Steady: Full scale value

Fluctuating: 0.9 x full scale value

Short time: 1.3 x full scale value

Permissible temperature


-40 … +65 °C with unfilled instruments

-20 … +65 °C with instruments with glycerine filling


Long duration: ≤ 100 °C

Short duration: ≤ 130° for instruments with glycerine filling and windows from instrument


Short duration: ≤ 260° for unfilled instruments and windows from instrument glass

If the pressure gauge is exposed to a medium or ambient temperature of > 100 °C,

temperature errors and damage to components should be expected. For long-term

operation of the instrument with medium or ambient temperatures

> 100 °C, we recommend the use of a diaphragm seal or an alternative heat-dissipating

physical design measure. WIKA employees are available for any technical questions and for

any application assistance you may require.

Temperature effect

When the temperature of the measuring system deviates from the reference temperature

(+20 °C): max. ±0.4 %/10 K of full scale value
