Understanding Electro-pneumatic Positioners

Electro-pneumatic positioners are control devices that are usually connected to actuated valves, in order to achieve the desired position during industrial processes. These positioners are built with an electro-pneumatic transducer which is responsible for receiving DC analog signals from the main control system. It is important to point out that some positioners do not have transducers, but they can always be upgraded to include this component. Positioners are available in a variety of series, with each one having its own advantages and disadvantages. It is up to you to carefully study these issues and then choose the products that are most suitable for your needs.

Why Electro-pneumatic Positioners are Necessary

Positioners are vital because they are able to detect very small errors, and correct these errors automatically. There are certain processes that may encounter minor errors from time to time, and this may result in ineffective use of energy or a slower production rate. In order to avoid such complications, it is highly encouraged that positioners are used together with the different valves in the system.

Another reason to keep in mind is that electro-pneumatic positioners are able to help a plant use energy more efficiently. It is true that most industrial processes are carried out to produce products that will help the client in one way or another. The producer of these products must also make a profit in order to keep the particular plant running, and that is why these positioners play an important role in keeping energy costs down. They ensure that all processes use the required amount of energy, without waste.

Another important point to mention is that positioners are able to help the system synchronize much better. Once this synchronization has been achieved, there are few complications that can arise. It is also worth noting that the production of the particular plant will achieve optimal results since all parts will be working in a complimentary manner.

How To Pick The Right Electro-pneumatic Positioners

When considering the best positioners to pick, you should pay close attention to several things. One of the things for you to think about is in the form of the valves that will use the positioners that you are about to buy. The type of valves in question must be determined first, and then the appropriate positioners can be selected.

The second thing is whether you wish to get upgraded positioners, or if the previous versions are able to serve you well. It is worth mentioning that previous versions are normally cheaper but not as effective as those that have been upgraded.

You should also pay close attention to the brand name of the electro-pneumatic positioners you wish to acquire. It is advisable to only buy products that have been designed by a reputable company. If you keep these points in mind, you will be able to make the correct decision during selection.
