Types of Pressure Transducer

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

Piezoelectric Transducer Working Principle

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

RTD Working Principle

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

Thermocouple Working Principle

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

Errors in Transducers

 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

Selection Criteria of Transducer

There are many ways to measurement of a physical quantity. While the selection of transducers, and how to select a transducer for a particular application, the following points should be kept in the mind.  Unfortunately, most transducers are not sensitive to just one quantity. If measurements are to be made under conditions where there is a likelihood of two or
