Sensors and Transducers
Sensors and transducers are critical components in modern measurement and control systems, converting physical phenomena into readable signals or vice versa. Understanding the types, working principles, and signal processing involved is essential for engineers and professionals handling measurement and automation technologies. This article provides a comprehensive overview of various sensors and transducers, their operating mechanisms, and signal conditioning techniques.
Sensors and Transducers
Types of Sensors
Sensors are devices that detect changes in the environment or within systems and respond by generating signals that can be interpreted by observers or instruments. Sensors are usually categorised based on the physical property they measure. Common categories include temperature, pressure, flow, and level sensors.

Module 3: Temperature Measurement (Contact & Non-Contact)
Introduction
Temperature measurement is a critical aspect of process control in industrial operations, influencing safety, product quality, energy efficiency, and process reliability. Whether monitoring turbine inlet temperatures in power plants, controlling furnace conditions in oil and gas refining, or measuring reactor core heat in nuclear plants, selecting the appropriate temperature measurement method is vital. This training module on "Temperature Measurement" provides an in-depth understanding of both contact and non-contact techniques used across various industries.
Section 1: Fundamentals of Temperature Measurement
Temperature is the measure of the thermal state of a substance, indicating its energy content. Accurate temperature measurement enables optimal process conditions and helps in preventing overheating or undercooling scenarios.
Two Primary Methods of Temperature Measurement:
Contact Methods: Instruments are in direct contact with the process medium. Examples include RTDs and Thermocouples.
Non-Contact Methods: Instruments detect emitted infrared radiation from the...
Webb Confirms Temperature Difference between Eternal Morning and Evening on WASP-39b
NASA Space Technology Astronomers using the NASA/ESA/CSA James Webb Space Telescope have obtained and analyzed morning and evening transmission spectra of WASP-39b, a hot-Saturn exoplanet orbiting a star some 700 light-years away in the constellation of Virgo. The spectra are best explained by models in which the evening terminator is hotter than the morning terminator by 177 K.This illustration shows what WASP-39b could look like, based on the current understanding of the planet. Image credit: NASA / ESA / CSA / Webb / J. Olmsted, STScI.WASP-39b is a hot gas giant that orbits the G7-type star WASP-39 with a period of 4.1 days.First discovered in 2011, the alien world has approximately the same mass as Saturn but is 50% larger.The planet’s extreme puffiness is related in part to its high temperature (about 900 degrees Celsius,...
