1. through the temperature converter into a standard analog signal sent to an analog interface (such as an inverter analog interface), and then make the human-machine interface and the inverter communication to read out the signal, and then the signal for data processing into an accurate temperature value can be, this can save a PLC.
2. The temperature sensor signal is directly connected to the Siemens S7200 analog module, the module is then connected to a CPU, and then use the touch screen to read out the temperature value, and then converted to the correct temperature value through data processing.
