Different physical processes are used to measure
temperatures. Temperatures can be read off directly on a scale, e.g. by the
expansion of a measuring medium. In industry, temperatures are often measured
electronically. The advantage of electronic measurement is that further
processing or transmission of signals to remote locations (controllers,
external displays) is easier.
The trainer can be used to carry out and compare different
temperature measurement procedures. The trainer includes liquid thermometers,
bimetal thermometers, as well as a thermocouple,a Pt100 resistance thermometer
and an NTC thermistor, each with different protective sleeves, for electronic
temperature measurement. A psychrometer with two liquid thermometers is used to
measure the relative air humidity.
