3 İ stanbul Technical University Actuators 1. Electrical 2. Hydraulic 3. Pneumatic Pneumatic actuators use air (safe, low-cost, readily available) or other gases under pressure Used to produce linear and rotary motions Usually used to control final control elements (to activate large valves etc.) Hydraulic systems can exert more force, but more expensive Drawback of pneumatics is compressibility of air

7 İ stanbul Technical University Why should we use pneumatics? Advantages: z Weight (they weight less than the motors) z Simplicity (easy to assemble and use) z To apply considerable forces with small elements z Easy to use z Modular z Reliable (shock resistant) Disadvantages: z Noise – due to the compressor z Compressor weight (big disadvantage) z Limited gas volume

14 İ stanbul Technical University Perfect Gas Laws Boyle’s Law: If the temp of a given amount of gas is held constant, the volume of the gas will change inversely with the absolute pressure of the gas. V1/V2 = P2/P1 Charles’ Law: If the pressure on a given amount of gas is held constant, the volume of the gas will change in direct proportion to the absolute temperature. V1/V2 = T1/T2 Gay-Lussac’s Law: If the volume of a gas is held constant, the pressure exerted by the gas is directly proportional to its absolute temperature. P1/P2 = T1/T2 General Gas Law: 11 2 2 12 P VP V TT =
