Another argument in favour of the ceramic measuring cell: it is a dry cell, i.e. free of oil. In the event of a diaphragm rupture, no substance can escape to contaminate – unlike with a metallic measuring cell, where oil often needs to be used as the transmission medium.
Planners and operators also take advantage of this when it comes to measuring aggressive and toxic gases, as safety plays a particularly important role in such cases. But even in applications with the VEGABAR 82 and 83 in acids and alkalis, VEGA can offer highly resistant materials for process fittings and measuring cell – and with a “Second line of Defense” as well. This means the measuring cell is separated from the electronics by a gas-tight, glass feed-through.
