What You Need to Know About Capsule Low Pressure Gauge

It is critical to understand the application of the instrument, especially capsule low pressure gauge. So we'll take the time to help you understand when and how to use this tool.

 

Understanding How They Work

Since the 1920’s, capsule gauges like this have been used for monitoring.

 

These capsule low pressure gauges got their name due to their inside structure. There are two internal pockets which act similarly to lungs and allows gas to be measured as the pressure changes with these pockets either contracting or expanding. As this change is detected, a deflection lever is activated and that allows the rotary movement to display the reading on the gauges front.

 

The nature of this tool allows for a precise reading to take place, making it a great option for you.

 

Applications For Capsule Low Pressure Gauge

Capsule gauges are found in applications that operate in a vacuum or very low pressures. These include, but are not limited to, the following:

Fan and blower monitoring

Filter monitoring

Low-pressure pneumatic systems

Vacuum pumps

Medical suction devices

Gas burners

Overpressure monitoring in clean rooms

 

Low pressure gauges are used in a variety of industries:

Medical equipment

HVAC

Oil and gas

Petrochemical

Power generation

Environmental technology

Mechanical engineering

 

A capsule low pressure gauge with brass wetted parts is suitable for most applications. For use with aggressive media, choose a stainless steel pressure gauge.

 

Important note: Capsule low pressure gauge can be used only for dry gaseous media. Due to the instrument’s vertical position and the very narrow passage into the capsule element, liquid media won’t be able to drain out completely. Any liquid that remains inside the capsule will create a hydrostatic load, which will result in a false pressure indication. To measure liquid media at very low pressures, use a diaphragm pressure gauge like the 43X.30, 43X.36, or 45X.50.

 

FAQ’S

Can Capsule Low Pressure Gauges measure absolute pressure?

Yes, Capsule Low Pressure Gauges can measure absolute pressure by evacuating the pressure chamber and sealing it hermetically, creating conditions similar to a near-perfect vacuum.

 

How do Relative Pressure Sensors Work in Capsule Low Pressure Gauges?

Relative Pressure Sensors apply the process pressure to the inside of the capsule, measuring close forces. The atmospheric pressure, or reference pressure, is located outside the capsule. One or more capsules can be used to measure relative pressure.

 

Can capsules be used for measuring liquids?

No, capsules cannot be used for liquids because they are not self-draining. Capsules are specifically designed for gas pressure measurement.

 

What are the types of pressure gauges?

There are various types of pressure gauges, including Bourdon Tube, Diaphragm, Capsule, Absolute, Differential, Bellows, and Manometer Pressure Gauges. Each class is designed for specific applications in commercial or industrial settings.

 

Where are Capsule Low Pressure Gauges used?

Capsule Low Pressure Gauges are used for pressure measurement at shallow pressures, especially for gaseous and aggressive media in harsh environments. They have a robust design with IP54 ingress protection, making them suitable for outdoor use.
