What If There's No Power - How Do I Control My Pneumatic Circuit?

With the advent of the small PLC's (programmable logic controllers), the Brand or the Pico to name only a couple, controlling pneumatic circuits can be achieved with high reliability, low complexity, and at a comparatively low cost with one of many at present accessible, simple to program controllers.

That is all effectively and good for the vast majority of purposes that occur in a plant environment that offers electricity. However what if yours would not? Or, what for those who would like to have a non-electrical compressed air circuit, one that's, perhaps, positioned in an explosive or fireplace hazard location?

Years in the past, there were no choices but utilizing air logic to control compressed air applications. For more modern applications which will have to function without electrical energy, air logic still provides a viable alternative.

There are commercially and available air logic components that will provide help to design the air-solely pneumatic circuit.

OR Gate

This device will enable an output management sign when both of {two} incoming air indicators are present. The output air signal is continuous so long as there may be an incoming air signal. That is helpful while you want to sequence a pneumatic operation, however don't desire it to occur until another operation is complete.

AND Gate

This machine will allow an output sign only when there are {two} input air indicators received. The output air sign is continuous as long as there are {two} incoming air signals. This is helpful whenever you want to sequence a pneumatic operation, however don't need it to occur until other operations are complete.

NOT Gate

Sends an output air sign repeatedly when the incoming air signal is absent. Any such machine is often used to make sure that a sequence can't happen until one other motion is complete.

PULSE

This system will allow a momentary output signal to trigger a sequence operation, and the output sign will drop after it "times out". This is helpful for simplifying control circuitry eliminating the potential for conflicting control air if the pneumatic circuit hasn't been designed properly.

TIMER

These units can either generate an outgoing sign for a selected time period or, delay an outgoing sign for a specific time frame when either receives in enter air signal.

INDICATOR

These devices are used when there is a have to have a visual indicator that there is compressed air present. Some may change color, others might have an indicator pin that pops up to show air is there. Of course, a stress gauge would do the same factor, but maybe it is likely to be beneficial to have the ability to see that there's air current from a distance?

POSITION SENSORS

By having an object interrupt an air move, or have the air circulate within the sensor uninterrupted, will produce an outgoing air signal.

These are just some of the numerous other air logic elements and gadgets commerically available. With these items, air logic can be utilized to build quite advanced air control circuits.

Warning: the compressing of air generates a great deal of water, and air / water borne contamination within the air traces to the plant which is usually a real drawback for downstream air components.

Air logic gadgets are just such downstream air components. It is essential for his or her dependable operation to have the air provide to these sensitive management components clean and dry. Failure to supply air of enough quality will ensure that the air logic management circuit won't perform to design or expectation.

Can it be used in applications which include opening and closing the gate of a hopper containing tons of sand, instead of pneumatic actuators?

yes...

Hydraulic actuators were used
