Summary
Well done! You have successfully completed this chapter, which is an important stage of industrial automation. You should now understand process control and be able to explain various process control terms and understand ISA symbols according to ISA5.1. You have also learned about the sensors and transmitters required for temperature measurement, level measurement, pressure measurement, and flow measurement, which are common in industry. You should now be able to wire a temperature sensor and transmitter, level transmitter, and pressure transmitter to generate a 4- to 20-mA analog output, which is very important for process control. We have also learned how to keep the temperature of a heater at the desired level by using a temperature controller.
The last section covered more advanced topics within the field of industrial automation, where we discussed the basic theory you need to know about analog input signal processing in a PLC (S7-1200), which includes reading analog...
