Abstract
This bachelor work deal with development of device for simulation of thermocouples. Concretely with design of simulation of J type thermocouple, which is controlled by application created for PC platform. The main part of hardware is microprocessor, that comunicates with computer by USB interface. On the basis of received data microprocessor with the assistance of bipolar current source controlled by D/A convertor sets desired value of thermoelectric voltage on measuringe resistor. Furthermore microprocessor by force negative voltage feedback regulates the value desired by user.
