Hi friends, In this article, I am discussing some important types of pressure transducer, pressure transducer working principle, advantages, disadvantages, and applications. So let us start. Pressure transducers are used to measure pressure. In a pressure transducer, firstly, the pressure is converted into a displacement by an elastic element like Bourdon tube, diaphragm, bellows, etc. And then […]
There is a large number of ratings associated with thyristors. These ratings are in terms of voltage, current, power, temperature and derivatives of voltage and current and time to switch on and off. In practice, it may not be necessary to give consideration to each and every rating to make choice of a thyristor. Thyristor
Hi friends, In this article, I am going to discuss the domestic refrigerator working principle and construction. You will find this article interesting and informative. So let us start. The common type of domestic refrigerator has a cabinet shaped with compressor, the condenser and receiver fitted in their basement. The expansion valve and evaporator coils are exposed

Electron beam welding in vacuum utilizes the kinetic energy of electrons traveling with high velocity in a high vacuum (10-3 to 10-5 mm Hg). When the electrons strike the surface of the metal, they give up the bulk of their energy as heat, and this goes to melt the metal. If the work is done in

The laser is a device that produces a concentrated coherent light beam by stimulating electronic or molecular transitions to lower energy levels. The word laser is an acronym for “light amplification by stimulated emission of radiation”. The laser beam is a highly concentrated source of energy which has many applications. It can be used for welding,

Properties and Applications of Soft Magnetic Materials Materials which have a steeply rising magnetization curve, relatively small and narrow hysteresis loop and consequently small energy losses for each cycle of magnetization are called soft magnetic materials. Soft magnetic materials are, therefore, employed in building cores for use in alternating magnetic fields. The commonest soft magnetic materials

Ferromagnetic materials have a crystal structure which means that they are made up of crystals. Every crystal of a ferromagnetic substance has a particular direction along which it offers high permeability and is, therefore, most easily magnetized. Such axes, along which the crystals have high permeability and are more easily magnetized, are called the “preferred”
Hi friends, In this article, I am discussing the “Creep in materials.” Types of creep and creep strength. So let us start. Metals will deform under steady service loads less than the short-time elastic strength if the loads are applied for a very long time at temperatures near the crystallization temperature. Apparently, the atoms tend
Hi friends, In this article, am discussing the properties of superconductors and the applications of superconductors. This article will provide you sufficient information about superconductors. The resistivity of most metals increases with increase in temperature and vice-versa. There are some metals and chemical compounds whose resistivity becomes zero when their temperature is brought
A data acquisition system (DAQ) is a computerized system that collects data from the real world, converts it into the form of electrical signals, and does required processing on it for storage, and presentation on computers. It acts as a bridge between the physical world and the digital realm. It captures physical quantities like temperature,
