摘要: This oil level control device is for a refrigeration system, the being attached between compressor and supply. The includes housing having an inlet communicating with supply outlet sump; solenoid valve controlling flow from into sump. A sensing chamber fixed probe providing proximity detection system detects in sump responds to change complex permittivity of as rises falls generate signal that controls maintain compressor. Circuitry provided input connected output sensor valve.
