Description
The temperature control system was designed and built for application in dielectric spectroscopy. It is based on dual-stage Peltier element that decreases electrical power and no cryogenic fluids are required. A proportional integral derivative controller was used to keep the temperature stability of the system. Temperature of the system was measure by a Pt100 temperature sensor. Effect of vacuum isolation and water cooling on accuracy and stability of the system were also studied. With incorporation of vacuum isolation and water cooling at 18 °C, temperature of the sample under test can be controlled in the range of -40 °C to 150 °C with uncertainty ± 0.02 °C.
