• Investigate the thermal characteristics of three electrical thermometry devices
• Explore the features and behavior of a closed loop digital temperature control system
The Thermoelectric Effects Apparatus consists of an oven containing a cooling fan, a massive metal block and electric heater supported on two thin struts, the three samples, and the control system sensor. A control unit provides the heating current and houses the digital temperature controller. The oven and the control unit are connected by three multi-pole cables.
The sample devices are a thermocouple, a three-pole metal resistor, and a thermistor. An insulated flask is provided to hold ice water for the cold junction of the thermocouple. The signals from the three sample devices can be read by any suitable measuring device provided by the user connected to the outputs of the control unit (for example, digital multimeters.)
The digital control system can be operated in P, PI, PD, or PID mode to show their characteristics when controlling the oven temperature with or without fan cooling. A wide range of parameters and alarms can be set to explore their effects.
