Data Acquisition and Power Supply of Multi-step Temperature Controller

摘要

The article introduces the design of the data acquisition and power supply of multi-step temperature controller. The power supply works stably and reliably. This data acquisition system possess a good linearity stability, because we adopt constant current source, temperature amplifier LM301, high precision 12 bit A/D AD574. As general temperature controller can only control a preconcerted temperature, in our actual
