Standard pressure gauge Ø 100 mm, G 1/2 radial bottom, -1 to 3 bar, plastic case, type 7304 - Riegler 101965

This standard gauge displays vacuum and positive pressure from -1 to 3 bar purely mechanically via a bourdon tube, so it stays readable without power. Nominal size Ø 100 mm, G 1/2 connection radial bottom.

Key benefits

• Ø 100 mm with bottom radial connection, G 1/2 male thread
• Plastic case, plastic window
• Medium and ambient temperature -20 to 60 °C
• Scale graduation 0.1 bar for accurate reading across -1 to 3 bar
• Accuracy class 1.6, equal to a permissible error of ±64 mbar over the span

Applications

Typical locations are lines and vessels that alternate between vacuum and positive pressure. Permitted media are gases and liquids without high viscosity or tendency to crystallise that do not attack copper alloy.
