Abstract
A pair of pressure sensors having their openings in diametrically opposed positions are mounted in and substantially parallel to the flow stream in a turbine type power plant for obtaining a differential pressure signal indicative of an incipient surge condition. Logic circuitry selects a threshold value, whereupon the signal is utilized to provide an output signal for taking surge corrective action.
