Standard pressure gauge Ø 160 mm, G 1/2 radial bottom, -1 to 9 bar, sheet steel case, type 8306 - Riegler 101986

This standard gauge displays vacuum and positive pressure from -1 to 9 bar purely mechanically via a bourdon tube, so it stays readable without power. Nominal size Ø 160 mm, G 1/2 connection radial bottom.

Why this gauge

• Ø 160 mm with bottom radial connection, G 1/2 male thread
• Sheet steel case, instrument glass window
• Medium and ambient temperature -20 to 60 °C
• Scale graduation 0.2 bar for accurate reading across -1 to 9 bar
• Accuracy class 1.6, equal to a permissible error of ±0.16 bar over the span

Typical use

It is typically used here: lines and vessels that alternate between vacuum and positive pressure. Media may be gaseous or liquid as long as they do not attack copper alloy, are not highly viscous and do not crystallise out.
