    摘要: A control apparatus, for measuring pressure in relation to a rotary screw compressor with capacity control means and a prime mover, including a pressure sensor to monitor the prime mover manifold pressure, and a series of relays which when tripped by the pressure sensor will engage a pressure mechanism to engage the capacity control means on the compressor. The pressure mechanism may be a hydraulic or a pneumatic pressure mechanism and the apparatus may further include a second pressure sensor to monitor the inlet gas pressure to the compressor and a third pressure sensor to monitor discharge pressure of the gas compressor.
