About Capsule-type pressure gauges

Capsule pressure gauges read low pressures in the millibar range, where a bourdon tube gauge is too coarse. The sensing element is a pressure capsule that deflects at very small pressure differences. Gauges in this group come in 63 to 100 mm nominal sizes with G 1/4 ET or G 1/2 ET connections.

What matters when choosing

• The measuring range comes first. It is quoted per article and should be picked so the normal working value sits around mid scale.
• Nominal size of 63 mm or 100 mm follows reading distance and available space. The larger dial allows a finer scale division.
• Case options are steel, CrNi steel 304 and CrNi steel 1.4301. The CrNi versions are the ones for damp surroundings, cleaning agents or outdoor mounting.
• The connection is G 1/4 ET or G 1/2 ET and has to match the measuring point. Connection position is stated per article.
• Medium temperature starts at -20 °C, with the upper limit between 60 and 100 °C depending on version.

Typical applications

• Monitoring of ventilation and extraction systems in the low pressure range
• Pressure indication on blowers and fans
• Gas and burner lines running at millibar level
• Test rigs where small pressures have to be read reliably
• Vessel and process monitoring in process engineering with slight positive pressures

Cases are steel, CrNi steel 304 or CrNi steel 1.4301, with production in Switzerland and Germany. The group holds 88 articles in the 63 and 100 mm nominal sizes.
