A thermocouple is a temperature sensor composed of two different metal wires joined together. When exposed to different temperatures at each end, it generates a voltage due to the Seebeck effect. This voltage is directly proportional to the temperature difference, thus allowing precise temperature measurement. Thermocouples find widespread use across Read more…
A strain gauge pressure sensor measures pressure by transforming applied mechanical force into an electrical signal. It works based on the principle that applying pressure to a material makes it to change shape. This leads to change in its electrical resistance. This change in resistance is to measured and correlated Read more…
INTRODUCTION of AIR COMPRESSOR in Pneumatic system. An air compressor is a mechanical device that transforms power into pressurized air using an electric motor, gasoline or diesel engine.It operates by drawing in air, compressing it, and then storing it in a tank at a higher pressure. This compressed air can Read more…
The Bernoulli’s theorem, named after the Swiss mathematician Daniel Bernoulli, is a fundamental principle in fluid dynamics. It describes the behaviour of an ideal fluid flowing in a streamline motion. It states that in a steady, incompressible flow of a fluid with no viscosity (or negligible viscosity), the total mechanical Read more…
Viscosity is the fundamental property of a fluid that describes its resistance to flow. Viscosity remains one of the most interesting and mysterious concepts in fluid dynamics. The word viscosity comes from the Latin word viscum, meaning “sticky,” which conveys a vivid image of a fluid’s reluctance to cascade smoothly. Read more…
Block diagram of a closed loop control system and open loop control system shows the arrangement of interconnected control and working component.Control components are the information processors.Working components are energy converter.
Working principle of hydraulic pumps-It convert mechanical energy by pushing the hydraulic fluid into the system. It some times called as generator.It is designed to give motion or flow of fluid. Pump push the hydraulic fluid into the system,because of resistance in fluid flow pressure developed. The pump never predetermine Read more…
Different types of pump in hydraulic systems are gear pump,Vane pump,etc. Types of pump in hydraulic Positive displacement pump Rotary pump Reciprocating pumps Non positive displacement pump Centrifugal pumps Axial flow pumps Radial flow pumps Rotary Pumps There are three types of rotary pumps. Gear pump Vane pump Screw pump Read more…
