52046 Measurement of temperature is an
important task in a large number of physical
processes. A transducer is a device which converts
the temperature information into an electrical
signal, usually voltage, for an automated
processing. A very wide variety of temperature
transducers are commonly available which differ
from each other with regards to these: Range of
operation, Sensitivity, linearity, Accuracy,
Stability, Repeatability and Speed of response The
present experiments have been designed to study
the input-output characteristics of some common
transducers like, thermistors (PTC and NTC),
thermocouple, semiconductor sensors and may be
extended to also study the temperature
coefficients of resistance.
