Peltier Thermoelectric Liquid Bath For Keeping Constant Temperature
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
