Know the Difference between Gauge Pressure and Absolute Pressure
Two pressure scales are utilized to measure pressure values in fluid power systems: a gauge scale and an absolute scale. The gauge pressure is the pressure indicated by a pressure gauge. It is a measure of the pressure with reference to the atmospheric pressure (1.013 bar or 14.7 psi) and it is not with reference... Continue Reading →
Configuring a Typical Pneumatic System
The schematic diagram of a typical pneumatic system is given in the accompanying figure. Basically the system is composed of a power source, control valves, and work elements. The power source can broadly be classified into: compressed air generation, primary air treatment, storage, air distribution, and secondary air treatment. A compressor is a device for...

Know the Most Economical Pressure in Pneumatics
What is the Most Economical Pressure in Pneumatics? Pneumatic systems have been developed and progressed comparatively as a low-pressure system. Pneumatic air consuming devices such as cylinders and rotary actuators are designed for the maximum operating pressure of 8 to 10 bar [115 to 145 psi]. However, practical experience has shown that 6 bar [90... Continue Reading →
The Essence of Programmable Logic Controllers (PLCs)
A programmable logic controller (PLC) is a modern device that can be used to control the work process in a machine or an appliance. The operations involved in the work process are carried out by some kind of actuators such as electric motors, pneumatic actuators, hydraulic actuators, etc., which are in turn controlled by final...

How to Develop Multiple-actuator Pneumatic Circuits Using the Cascade Method?
Most of the practical pneumatic systems involve the use of multiple actuators (cylinders, semi-rotary actuators, etc) which when operating in specified sequences carry out the desired control tasks. Double-pilot directional control (DC) valves are used as final control elements to control the forward and return strokes of the actuators. Sensors are used for confirming the... Continue Reading →
