Abstract

The disclosure describes a thermal density sensor for preventing the start-up of a compressor motor operatively connected to the piston and cylinder means of a compression mechanism when the temperature of the compression mechanism is below a predetermined value to prevent damage to the running parts of the compression mechanism due to inadequate lubrication. Control circuitry for operating the compressor motor is contained in a single control box on the compressor so that the wiring of the circuitry is simplified. The control circuitry is entirely factory wired and the circuitry is maintained in a tamper-proof environment.
