Temperature is a principle parameter that needs to be monitored and controlled in most engineering applications such as heating, cooling, drying and storage. Temperature can be measured via a diverse array of sensors. All of them infer temperature by sensing some change in a physical characteristic be it a thermal expansion, thermoelectricity, electrical resistance or thermal radiation. There are four basic types of temperature measuring devices, each working on a different principle: Mechanical (liquid-in-glass thermometers, bimetallic strips, bulb and capillary, pressure type etc.); Thermocouples; Thermo-resistive (RTDs and thermistors) and Radiative (infrared and optical pyrometers).

Each of these will be discussed in this course. The course is written in user friendly language and the theoretical equations are kept to a minimum. The basic aspects are discussed wherever deemed fit.

This course is aimed at electrical, instrumentation and control engineers, energy auditors, O & M professionals, contractors, estimators, facility managers and general audience.
