An inverting converter, also called a reverse converter, is a signal converter that inverts the relationship between the input and output signals.
For example, in a vacuum gauge, the output signal and the degree of vacuum have an inverse relationship. Therefore, when displaying the sensor signal on a meter, it is necessary to use an inverting converter to invert the signal.
Additionally, for displaying the movement distance of an object (DC 4–20 mA) as 0.0–10.0m on a panel meter, the usual setup would display the current distance traveled. By using an inverting converter, however, you can display how much distance remains until 10.0m is reached.
Similarly, in a circuit that measures the water volume inside a tank using a level gauge, inserting an inverting converter allows the signal to be changed to indicate how much more water can be added to the tank.
