Abstract
A cutoff switch for refrigerant recovery storage container will indicate when the storage container reaches a maximum safe level. The switch will disable the compressor to prevent further recovery of refrigerant. The switch is located in a sensor housing that couples to a magnet housing. The magnet housing mounts to the upper end of the storage container and connects with the float. A magnet will move vertically in response to movement of the float. At least one Hall Effect sensor mounts in the sensor housing. The Hall Effect sensor will sense the presence of the magnet and disable the compressor accordingly.
