The model PG28 Bourdon tube pressure gauge with wetted parts from Hastelloy C276 is particularly suitable for applications with aggressive media.
Hastelloy C276 belongs to the group of highly corrosion-resistant nickel-chromium-molybdenum-tungsten alloys and is notable for its high resistance to crevice corrosion, pitting and stress corrosion cracking in corrosive, oxidising and reducing media.
WIKA also produces the model PG28 in a particularly safe version with a solid baffle wall (Solidfront). This 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 user is protected at the front side, as media or components can only be ejected via the rear of the case.
As an alternative, WIKA offers diaphragm seals of models 990.34 and 990.10 as well as model 4 diaphragm pressure gauges in a Hastelloy version. Diaphragm seals are always the first choice for safety-relevant applications.
The QR code on the dial allows instrument-specific information such as the serial number, the order number, certificates and other product data to be retrieved from the internet easily and in the long term.
