The model 33x.30 high-quality test gauge has been specifically designed for increased safety requirements during high-accuracy pressure measurements and is suited for calibration tasks. With an accuracy class of 0.6 %, the Bourdon tube pressure gauge is suitable for testing industrial type pressure gauges or for precision measurement in laboratories. Optionally, an accuracy class of 0.25 % is possible for pressures = 400 bar.
The wear-resistant precision movement, the wetted parts and the case are made from high-grade stainless steel. WIKA manufactures and qualifies the Bourdon tube 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 a 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 conditions (e.g. vibrations), all instruments are also available with an optional liquid filling.
The optimal readability of the instrument, with a nominal size of 160 mm, is achieved via a knife edge pointer and a dial with fine divisions. Supported through the optional mirror band scale, the parallax error can be eliminated.
For this instrument, an optional DKD/DAkkS calibration certificate can be generated. Safe storage and transport is ensured by a transport case (accessory).
