232.34 pressure gauge with bourdon tube WIKA

Description

232.34 WIKA bourdon tube pressure gauge is used for pressure measurement of gaseous and liquid media.

This high quality Bourdon pressure gauge has been designed specifically for the increased safety requirements of the process industry.

By using stainless steel materials for the wet parts as well as highly resistant plastic for the casing, the 232.34 achieves excellent corrosion resistance. This makes the instrument ideal for liquid and gaseous media, even in aggressive environments.

Scale ranges from 0 … 0.6 bar to 0 … 1000 bar provide 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 consists of a shatter-proof plastic window, a solid partition between the measuring system and the dial, and a vent. In the event of a failure, the operator is protected at the front, as the media or components can only be extracted through the back of the housing.

In harsh working conditions (e.g. vibration), all instruments are also available with an additional casing refill.
