Thermography is mainly used in an infrared measuring instrument like an infrared camera, to detect and measure the thermal energy releasing from an object. Thermography is commonly used in industry for predictive protection, condition measurement, quality assurance, and forensic inquiry of electrical, mechanical and structural systems. Thermography is used in non-contact were it uses remote sensing, maintain the user out of danger and does not interrupt ahead or affect the object at all.

It is used as two dimensional were the Assessment among areas of the object is possible. The image allows for outstanding indication of the object and Thermal patterns can be imagining for analysis. Thermographies used in real time were it allows very fast scanning of fixed objects. It enables to capture of fast moving objective. And it allows capturing of fast changing thermal patterns. Some of the disadvantages of thermography are like Due to the low quantity of thermal cameras; quality cameras often have a high price range. When we use thermography we can only able to directly sense the surface temperatures

Pneumatic cylinders are mechanical device which produce force, often in combination with movement and are powered by COMPRESSED GAS. Once actuated, compressed air enters into the tube at one end of the piston and, hence, imparts force on the piston. Consequently, the piston becomes displaced (moved) by the compressed air expanding in an attempt to reach atmospheric pressure.types of air cylinders are Single acting cylinders that is use the force imparted by air to move in one direction and a spring to return to the home position and double acting cylinders use the force of air to move in both extend and retract strokes.They have two ports air in, one for outstroke and one for instroke. Air cylinders are available in a variety of sizes and can typically range from a small 2.5mm air cylinder, which might be used for picking up a small transistor or other electronic component, to 400mm diameter air cylinders which would impart enough force to lift a car.
