Overview
The capsule (diaphragm-capsule) pressure gauge measures micro pressure and negative pressure of non-corrosive gases, with low ranges from 0-6KPa up to 0-100KPa and dial sizes of 3″ (60 mm), 4″ (100 mm) and 5″ (150 mm). Accuracy class is 2.5.
Its capsule sensing element is designed for very low gas pressures that ordinary Bourdon-tube gauges cannot resolve, making it the standard choice for boiler draft, gas pipelines and burner monitoring. A stainless steel version is available for processes with higher corrosion-resistance demands.
Available ranges are 0-6KPa, 0-10KPa, 0-16KPa, 0-25KPa, 0-40KPa, 0-60KPa and 0-100KPa, with connection threads of 1/4″ and 3/8″ in BSP, BSPT and NPT standards plus M14x1.5 and M20x1.5.

FAQ
What pressures can a capsule gauge measure?
It measures micro pressure and negative pressure of non-corrosive gases, with ranges from 0-6KPa up to 0-100KPa — far lower than standard Bourdon-tube gauges.
Is there a corrosion-resistant version?
Yes, a stainless steel version is available for processes with higher corrosion-resistance demands.
