What does a modulating pressure control do
It's Angle modulated system where the amplitude remains constant & frequency & phase varies with respect to modulating signal.
modulating signal is the low frequency signal .so we cant transmit for a long distance.so we go for modulating the signal either by modulating the amplitude or frequency or phase of the signal.
Modulating controls are used for pressure control, rating and for mixing of liquids at different temperature.
Amplitude Frequency
Repetition rate of an AM envelope refers to the frequency of the modulating signal thus the shape of the envelope is identical to the shape of the modulating signal.

Modulating Signal,
It is a device or electronic circuit that changes the frequency of an oscillator according to the amplitude of modulating signal. For instance, if the modulation is linear, the modulator changes the frequency proportional to the amplitude of the modulating voltage.
