The pre-volume deflagration flame arrester for pressure measuring arrangements from WIKA has an IECEx approval in addition to its ATEX approval is the only one of its kind. It is thus gaining broad international acceptance.
The safety device (model 910.21) fulfils the requirements of the harmonised standard
EN ISO 16852:2016 “Flame arresters …”. WIKA combines them with Ex-approved measuring instruments and diaphragm seal systems to form a fixed unit. Such a measuring arrangement is suitable for mounting to zone 0.
The pre-volume deflagration flame arrester prevents a potential passage of the flame from the instrument into the process side, in the event of a failure. A marking on the measuring arrangement indicates the point at which the protected side begins.
• WIKA products are marketed in Ireland through Instruments Technology.
