Standard pressure gauge Ø 160 mm, G 1/2 radial bottom, 0 to 4 bar, sheet steel case, type 155 - Riegler 101991

This standard gauge displays positive pressure from 0 to 4 bar purely mechanically via a bourdon tube, so it stays readable without power. Nominal size Ø 160 mm, G 1/2 connection radial bottom.

Advantages

• Accuracy class 1.6, equal to a permissible error of ±64 mbar over the span
• Ø 160 mm with bottom radial connection, G 1/2 male thread
• Sheet steel case, instrument glass window
• Red reference pointer to mark a set point or limit
• Medium and ambient temperature -20 to 60 °C
• Scale graduation 0.1 bar for accurate reading across 0 to 4 bar

Specifications

Applications

It is typically used here: compressed air networks, air service units, regulators and compressors. Suitable for gaseous or liquid media that do not corrode 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 1.33 and 2.67 bar.
