Abstract:
A closed stainless steel tube is used to provide pressure and media isolation between the core and coils of a sensor in the form of a variable core transformer. The core is connected to and moved with a slide valve of a screw compressor and its actuating piston. The current output from the secondary coil is converted into a voltage, linearized and communicated to a microprocessor for controlling the position of the slide valve and thereby the loading of the compressor.
