DESCRIPTION:

The setup consists of a Heat source controlled with the help of digital temperature controller at any preset value. A thermocouple pocket is provided to insert the thermocouple in it. The time constant of different thermocouple can be calculated with the set-up. A Heat sink is fitted to cool down the thermocouple. All components are assembled on a base plate to form table top set-up.

The present set-up has a facility to interface the system with computer which enables to log the experimental data using computer. The educational software and data-logging package has been developed for unit. The software environment base is of Lab view of NATIONAL INSTRUMENTS, USA. This software is compatible to interfacing unit designed by “Lab smith”. This software package provides a comprehensive educational software environment within which the investigations can be performed. This software is capable to tabulate the sample readings according to the requirement of experiment under study and results obtained can be compared. The real time data acquisition can be done by interfacing the set-up with computer using software. Software allows the user to have control on data logging, printing the stored data, preparing spread sheets in Excel etc.

EXPERIMENTATION:

• To determine time constant of a given thermocouple.
