The VEGACAL 65 is an altitude detector for use in all businesses. The partially insulated probe is perfect for the size of mass solids and can as well be employed in non-conductive fluids, for example, oil. The established assembly guarantees high functional protection. Advantages include extended life span and abridged preservation need during strong automatic structure, high flexibility with a shortenable probe and maximum use of the vessel, since size is related to the total probe area.
