Standard pressure gauge Ø 80 mm, G 1/2 radial bottom, 0 to 40 bar, plastic case, type 139 - Riegler 101959

For high-pressure air the Ø 80 mm standard gauge gives a direct reading across 0 to 40 bar. It connects via G 1/2 radial bottom.

Why this gauge

• Scale graduation 1 bar for accurate reading across 0 to 40 bar
• Accuracy class 1.6, equal to a permissible error of ±0.64 bar over the span
• Ø 80 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

Applications

Typical locations are high-pressure air, test benches and water or gas lines. Media must be compatible with copper alloy, not highly viscous and non-crystallising, gases and liquids are both possible. For good readability the usual working pressure should sit in the middle third of the scale, here roughly between 13.3 and 26.7 bar.
