The pressure sensor is the signal after compression. The hydraulic setting is the pressure and velocity signal that is set up by the pressure valve and the proportional valve first
The pressure sensor is subject to pressure, outgoing current, and voltage signals.
No, as long as the power output signal will continue, the size of your setting range, for example: the upper limit is set to +100bar to -100bar, 4~20mA or 10V + output signal, when the pressure is 0, still have to output 8mA or 0V sensor signal output (note that 0V does not represent the actual output, he will the shock at 0 points around the small range).
