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 materials and the robust design are geared to applications in the chemical and process engineering industries. Thus the instrument is suitable for liquid and gaseous media, also in aggressive environments. Scale ranges of 0 … 0.6 to 0 … 1,600 bar [0 … 10 to 0 … 20,000 psi] ensure the measuring ranges required for a wide variety of applications.
WIKA manufactures and qualifies the pressure gauge in accordance with the standards EN 837-1 and ASME B40.100. 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 operator is protected at the front side, as media or components can only be ejected via the back of the case. 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.
