Click on the link for the Instrumentation notes it includes mainly two units as (1)Transducers and Sensors and (2)Industrial measurements. Some more topics will be covered soon or later. You can also demand as per need.
Strain gauge is a device used to measure strain of the object. Before going into details of it, let’s see something about strain. What is Strain? Strain is the amount of deformation experienced by the body in the direction of force applied, divided by the initial dimensions of the body. More specifically, strain (ε) is […]
In a measurement system the transducer (or a combination of transducers) is the input element with the critical function of transforming some physical quantity to a proportional electrical signal. So, selection criteria of transducer play an important role for having accurate results. The first step in the selection procedure is to clearly define the nature
In instrumentation transducers play a vital role. In this article the transducer and its classification is discussed. Basically, transducer is defined as a device, which converts energy or information from one form to another. These are widely used in measurement work because not all quantities that need to be measured can be displayed as easily
Signal conditioning is a process of data acquisition, and an instrument called a signal conditioner is used to perform this process. Data acquisition is the process of sampling signals that measure real world physical conditions and converting the resulting samples into digital numeric values that can be manipulated by a computer. Signal conditioning is a process
A piezoelectric transducer (also known as a piezoelectric sensor) is a device that uses the piezoelectric effect to measure changes in acceleration, pressure, strain, temperature or force by converting this energy into an electrical charge. The piezoelectric material is one kind of transducers. When we squeeze this piezoelectric material or apply any force or pressure,
What is Thermal Conductivity? Thermal conductivity refers to the ability of a given material to conduct or transfer heat. There are many techniques of Thermal conductivity measurement, in this article two main techniques are explained. Thermal conductivity is generally denoted by the symbol ‘k’ but can also be denoted by ‘λ’ and ‘κ’. The SI unit of
Smoke and fire detection can be done using two types of devices, “Heat detectors” and “Smoke detectors”. Heat detectors generally detect the heat that comes as a result of combustion. The devices trigger an alarm when they sense a rapid rise in temperature or when a certain temperature is reached. A smoke detector is an

What is Humidity? Humidity is the amount of moisture or water vapour present in the atmospheric gas. The more water vapour in the air, the higher the humidity. Humidity depends on the temperature and pressure of the system of interest. Humidity depends on the temperature and pressure. In this article, Humidity measurement is explained. The
A popular and non-destructive thickness measurement technique is generally employed to calculate the thickness of a material from one side. This technique is called ultrasonic thickness gauging. Non-destructive Testing (NDT) use beams of waves of short wavelength and high-frequency, transmitted from a small probe and detected by the same or other probes. Such waves can
Telemetry The term “Telemetry” derived from two words “Tele” and “metron”. “Tele” means over a long distance or far and “metron” means to measure. Therefore, telemetry is the measurement of quantities from a long distance. Following article focuses on Electrical Telemetry. Definition: Telemetry is a process by which data collected or measurements are made at
