About Standard pressure gauges

Standard pressure gauges display pressure at the measuring point without auxiliary power, so the reading stays available even if the controller drops out. These bourdon tube gauges cover ranges up to 600 bar in nominal sizes from 40 to 160 mm. The connection is G 1/8, G 1/4 or G 1/2 male.

What matters when choosing

• Max. measuring range: Full-scale values go up to 600 bar. Pick the range so that normal working pressure does not sit at the end of the scale, otherwise readability suffers and the bourdon tube works permanently at its limit.
• Diameter: From 40 to 160 mm. Small cases suit control cabinets and air preparation units, large sizes are needed where the value has to be readable from several metres away.
• Thread: G 1/8, G 1/4 and G 1/2 male are available. The size follows the measuring point, not the case diameter.
• Housing: Sheet steel or plastic. Plastic is the lower-cost option for dry indoor use, sheet steel is chosen where mechanical load is expected.
• Medium temperature: The group is rated from -20 to 60 °C. Hotter media need a siphon or cooling section so the measuring element stays within its limit.

Typical applications

• Indication on air preparation units and pressure regulators in compressed air systems.
• Compressor stations and distribution headers where line pressure is checked.
• Test rigs and assembly fixtures running at a fixed working pressure.
• Hydraulic power units and hand pumps in the upper pressure range.
• Vessels and pipework that require a permanently visible reading.
