2.2 Description
All wetted parts (process connection and pressure element) of the model
2 pressure gauge described below are manufactured from copper alloys
and/or stainless steel. The nominal size (NS) of 100 mm or 160 mm
stated is a rounded value referred to the case diameter.
Single and duplex pressure gauges
The model PG21BP-2 is a duplex pressure gauge, all other models
described here are single pressure gauges. Single pressure gauges
are used for one pressure line and duplex pressure gauges for two
independent pressure lines. The duplex pressure gauge combines two
single pressure gauges in one case with 2 process connections and
indicates both pressure values via 2 pointers (red and black) on one dial.
