Assembling temperature sensors: thermocouples and resistance temperature detectors RTD (Pt100)

Temperature is one of the most common physical quantities (measurand) to be measured in experimental investigations, monitoring and control of building indoor environment, thermal comfort and building energy performance.
The most common temperature sensors are the thermocouples and the resistance temperature detectors (RTDs). These analog sensors are cheap, accurate, durable and easy to replace or to repair. The cable of these sensors can easily be shortened or extended. These sensors have a simple, monotonic and stable correlation between the sensor’s temperature and their resistance/voltage output, which makes them ideal for temperature measurement with electronic logging equipment.
This technical report aims at providing clear guidelines about how to assemble and mount type-K thermocouples and Pt100 RTDs. These are the most common temperature sensors used in the Laboratory of Building Energy and Indoor Environment at the Department of the Built Environment of Aalborg University.
