The regulator for single-stage centrifugal compressors contains a sensing unit, in which pre-surge conditions trigger a signal, and a unit to amplify and convert this signal to a force, which activates the anti-surge device. To improve the reliability of the regulator, its sensing unit is made in the form of two pressure transducers mounted aft of the compressor impeller at any distance other than the impeller blade pitch, thus picking up the variation in the pressure spectrum behind the impeller to generate an electrical signal.
