This patent describes an apparatus for controlling the level of steam condensate in a steam retort comprising: drain valve means operable to regulate drainage of the condensate from the retort; and control means for operating the drain valve means in response to the condensate level in the retort, the control means comprising: sensing means for providing a first signal when condensate rises to a predetermined level to effect opening of the drain valve means and for providing a second signal when condensate falls below the predetermined level to effect closing of the drain valve means; the sensing means comprising magnetic float switch means comprising: a non-magnetic steam having a chamber therein and extendable into the steam retort in a fixed position; a magnetic reed switch disposed within the chamber in the stem; means for mounting the reed switch in a fixed position within the stem; a float movably mounted exteriorly of the steam and movable in response to the level of the condensate in the steam retort; and a magnet connected to the float and movable in response thereto for effecting operation of the reed switch.
