Peltier Thermoelectric Liquid Bath For Keeping Constant
Temperature
Principle of Peltier Device
A Peltier deivice (thermoelectric module, thermoelectric device) is
a plate type element, inside which P-type semiconductors and N-Type
semiconductors are located alter-nately. If direct current is
supplied to the Peltier device , heat is transferred inside the
device , and one face generates heat and increases temperature
while the other face sucked heat and decreases temperature .
Therefore, changing the direction of the current supplied to the
Peltier device and achieve heating and cooling operation . This
method has a fast response and can shift quickly between heating
and cooling, so temperature can be controlled very precisely .
Temperature sensor
Accurate display by measuring the circulating fluid with a
temperature sensor directly
