What is RTD and its working principal:- RTD stands for Resistance Temperature Detector. It is a type of temperature sensor that measures temperature by sensing changes in electrical resistance.It works on positive temperature co-efficient. The working principle of an RTD is based on the fact that the electrical resistance of metals changes with temperature. An RTD typically consists of a length of fine wire made from a platinum, nickel or copper alloy. As the temperature of the wire changes, so does its electrical resistance. This change in resistance can be measured and correlated to temperature using a calibration curve. RTDs are very accurate and stable over a wide temperature range, making them popular in a variety of applications, including industrial and scientific measurements. They are often used in applications where precise temperature control is necessary, such as in laboratory and industrial heating systems, as well as in temperature measurement and control systems in the
What is instrumentation and control: Instrumentation is a branch of engineering that we deals with the process variable and measurement of various parameters like:‐ Instrumentation refers to the process of using tools or devices (instruments) to measure, control, or monitor various physical, chemical, or biological variables in a system. This can include anything from measuring the temperature or pressure of a system, to monitoring the flow of a fluid, to analyzing the composition of a sample. Instrumentation is commonly used in many fields, including science, engineering, medicine, and manufacturing, to ensure that systems are functioning correctly, to troubleshoot problems, and to optimize performance. The instruments used in instrumentation can range from simple tools like thermometers and pressure gauges to complex systems like spectrometers and chromatographs. 1. Pressure. 2. Flow. 3.
