Standard pressure gauge Ø 100 mm, G 1/2 radial bottom, 0 to 25 bar, plastic case, type 149 - Riegler 101976

This standard gauge displays positive pressure from 0 to 25 bar purely mechanically via a bourdon tube, so it stays readable without power. Nominal size Ø 100 mm, G 1/2 connection radial bottom.

Advantages

• Ø 100 mm with bottom radial connection, G 1/2 male thread
• Plastic case, plastic window
• Red reference pointer to mark a set point or limit
• Medium and ambient temperature -20 to 60 °C
• Scale graduation 0.5 bar for accurate reading across 0 to 25 bar
• Accuracy class 1.6, equal to a permissible error of ±0.4 bar over the span

Typical use

Typical locations are high-pressure air, test benches and water or gas lines. Gases and liquids can be measured as long as they do not attack copper alloy, are not highly viscous and do not crystallise. For good readability the usual working pressure should sit in the middle third of the scale, here roughly between 8.33 and 16.7 bar.
