LEAT-8 Temperature sensor and semiconductor refrigeration temperature control

Understanding and testing the performance of temperature sensor is an essential part of college physics experiment, but most of the experimental instruments only have the ability to do experiments above the ambient temperature. Fd-tm temperature sensor test and semiconductor cooling temperature control experimental instrument have the function of semiconductor cooling, so that it can do experiments below the ambient temperature. This instrument mainly tests the performance of temperature sensor AD590 (a variety of temperature sensors can be added according to the requirements) and understands the performance of semiconductor refrigeration reactor.

Experiments

1. Learn the principle of semiconductor refrigeration;

2. Measure the characteristics of current mode temperature sensor AD590;

3. Learn the principle and adjustment method of intelligent temperature control.
