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,
Hi friends, In this article, I am discussing the piezoelectric effect, piezoelectric transducer working principle, its working, and applications. You will find this article informative and interesting, I hope so.The Piezoelectric transducer is an active transducer. It is generally used to convert mechanical stress or pressure into an electrical signal. These physical quantities cannot be measured
Hi friends, In this article, I am going to discuss the RTD working principle, its construction and applications. It is also known as a resistance thermometer. A resistance temperature detector is a passive resistive transducer. It is used to measure the change in temperature. RTD Working Principle As we know that every metal has a definite
Hi friends, In this article, I am going to describe you strain gauge working principle, gauge factor and strain gauge load cell working. A strain gauge is a passive transducer, that converts mechanical displacement into the change of resistance. A strain gauge sensor is a thin wafer-like device that can be attached to a variety of materials
Hi friends, In this article, I am going to discuss the thermocouple working principle, its types and properties. Thermocouples are the temperature sensors which are extensively used for the measurement of the temperature variations. They sense the temperature and the temperature is further measured by other instruments after sensing it. As they convert a non-electrical quantity (temperature) into
In this article, I am going to discuss the NTC thermistor working principle, its characteristics, and its applications. So let us start. A thermistor is a special type of resistor whose resistance changes with the change in its body temperature. These are of two types: PTC Thermistor: Positive Temperature Coefficient (PTC) thermistor, is made up
Hi friends, in this article, I am going to discuss about the lux meter working principle and its application. We have to measure light in many tasks. For this, the Lux meter should be used. To measure the light accurately, a lux meter is a very suitable device. It is calibrated to read directly in lux. The
The errors in transducers occur because they do not follow, the input-output relationship given by qo = f(qi) The error can be expressed in terms of either input or the output quantity. Four types of errors which occur usually are as under: Errors in Transducers 1. Scale Error The scale error comprises of four different types
