Study Of Temperature Transducers

We offer Study of Temperature Transducers, STT-01usefull for control labs. Measurement of temperature is an important task in a large number of physical processes. A transducer in 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 there:
(a) Range of operation
(b) Sensitivity and linearity
(c) Accuracy, Stability and Repeatability
(d) Speed of response
The present experiments has 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.
