50mm Low Pressure Capsule Pressure Gauge 80 mmH2O Brass Internals Bellows Manometer
Description
Bourdon tube pressure gauges have range limitations with the lowest range being 10 psi. Any time you need to measure below that range you will need a different sensing element. When you need to measure very low pressure or vacuum, low pressure gauges with a capsule design can measure as low as 1” H2O.
A capsule sensing element consists of two corrugated metal discs of brass or stainless steel fused together. A change in pressure will cause the discs to expand or contract, and this motion is transferred to the indicator through a pinion movement mechanism.
You can use this cost-effective gauge to measure low pressure very precisely with accuracies up to ±1.0%. The case size has a direct impact on accuracy. The capsule element is placed vertically inside the case of a low pressure gauge. The lower the measured pressure is, the larger the area of the diaphragm and the larger the case diameter.
Applications
Low pressure gauge for applications in a controlled environment
Ideal for measuring pressure, vacuum in medical, environmental, and laboratory applications for content and filter monitoring
For gaseous, dry and non-aggresive media
Special features
Front zero adjustment
Special connections on request
