ABSTRACT:
In the operation of a contact-type probe for sensing the level of glass in a tank or furnace, an arrangement is provided which will move the probe into contact with this molten glass at a relatively slow rate. After contact with the glass, the probe is quickly withdrawn from contact with the molten glass, the quick withdrawal being provided in the two embodiments. The first, by exhausting air from a diaphragm motor used to advance the probe and in the other embodiment electrically retracting the probe by the use of a solenoid.
