What is the working principle of stainless steel air pipeline electric heater?

The working principle of stainless steel air pipeline electric heater is: the measurement, adjustment and control loop is composed of digital display temperature regulator, solid state relay and temperature measuring element. In the process of electric heating, the temperature measuring element sends the electric signal of the outlet temperature of the pipeline heater to the digital display temperature regulator for amplification, displays the measured temperature value after comparison, and outputs the signal to the input end of the solid state relay at the same time, thus controlling the heater and making the control cabinet have good control accuracy and adjustment characteristics. The pipeline heater can be remotely started and shut down by interlocking device.
