A Non-engineer’s Guide to Pneumatic Controller

Engineering people know what a pneumatic controller is. Unfortunately, to non-engineers, it is a term that connotes a lot of confusion. That is understandable. We are not engineers but sometimes it is good if we know something about it for the sake of learning. In this section, we will discover more about what a pneumatic controller is.

Pneumatics is an engineering branch that tackles pressurized air or gas. The pneumatic system industry uses compressed air. The pneumatic system can  be manual or automatic controlled with solenoid valves. Solenoid valves are flexible, safer (than electric motors) and low cost.

applications of a pneumatic controller

Here are other things that you need to know about pneumatic controller:

What are the different applications of a pneumatic controller?

There are many applications of a pneumatic controller. It is an essential part of the safety of passengers as it can be found in the air brakes of trucks, buses, and trains. It is even used in compressed air vehicles like airplanes and helicopters. The famous application that is in Heating Ventilation and Air Conditioning control systems.

Other applications of pneumatics are found in pipe organ, mail systems, tire, vacuum pump, pressure switch, pressure sensor, pressure regular and many more.

What are the gases used in a pneumatic system?

You already know that pneumatics use pressurized air or gas. For fixed (immovable) installations like factories, they compress atmospheric air. As for vehicles, they use compressed carbon dioxide.

There are concerns about the leaking of compressed nitrogen and carbon dioxide. These are asphyxiation hazard. It means you can be suffocated.

What is the difference between hydraulics and pneumatics?
Pneumatics and hydraulics are using liquid under pressure to transmit power. Pneumatics use compressed gas while hydraulics use oil. Industrial pneumatics can hold pressures of 80 to 100 pounds per square inch (PSI). Hydraulics on the other hand use up to 5,000 PSI.

What are the advantages of pneumatics and hydraulics?

The pneumatic system is considered by most industries because of its simplicity. Machines with pneumatics are designed with cylinders and are operated through on-off control. Aside from that, the pneumatic system is reliable because it demands little maintenance. Most of all, pneumatic is safer compared to hydraulic. New machines now are overload safe.

As with hydraulics, it is capable of providing higher forces or higher loads. Hydraulics use oil and it does not absorb other supplied energy. Compared to pneumatics, hydraulics is exceedingly responsive. It can also generate more power than pneumatics. More importantly, it can do many things at a time – lubricate, cool and transmit power.

What is pneumatic logic?

The pneumatic logic system is sometimes called pneumatic controls or air logic control. It regulate the industrial process of relay or booster units, latching units, fluidics, timer units and sorteberg relay. Industrial processes utilize pneumatic logic because it is reliable. Machines these days replace pneumatic logic with electronic controls. This is because of its precision, power, and compactness.

Now that you these about the pneumatic controller, you can confidently say that you know something about it. Aside from engineering, pneumatics can also be used in mining, construction, and dentistry.
