hi I am Pragati

after reading those answers i found two keywords which are
RTD & thermostat.

RTD(resistance temperature detector) is used only to display
the temperature of winding. PT100 is one of RTD in which at
0degc the resistance is 100ohms. As temp. increases the
resistance increases linearly.

other is thermostat, it is an thermal switch.
DMP is one of thermostat which is having particular temp.
rating like 150deg C or 160 deg C and so on
as temp. of winding crosses the rated the switch is operated
and circuit is disconnected. This will protect our winding
from burning.

so if only display of temp. purpose we can use RTD & for
protection from burning we can use thermostat.
