The intelligent temperature switch is an intelligent digital temperature measurement and control product that integrates temperature measurement, display, output, and control. This product features a fully electronic structure, with the front end using a PT100 temperature sensor. The output signal is amplified and processed by a high-precision, low-temperature amplifier, then fed into a high-precision A/D converter to convert into digital signals that can be processed by a microprocessor. The computationally processed signals control two switches to measure and control the temperature of the control system. This intelligent digital temperature switch is flexible to use, simple to operate, easy to debug, and safe and reliable.
