Severn Engineering Co., INC.
Severn Engineering was originally created for the purpose of developing and manufacturing a field instrument to test the magnetic permeability of feebly magnetic materials for the U.S. Navy Bureau of Ships. It was used in the Mine Sweeper Program during the Korean War. Mr. Gross and Mr. Ellinghausen were employed as civilians at the U.S. Navy Engineering Experimental Station (later the David W. Taylor Research Laboratory) in Annapolis, Maryland. Their area of research was the magnetic permeability of feebly magnetic stainless steel. The Navy's urgent need for a field instrument to measure magnetic permeability prompted the Bureau of Ships to talk to them about producing such an instrument. After resolving legal issues, Severn Engineering Company was founded and the Severn Gage was designed. The Navy then placed an order for 317 instruments. Other orders soon followed from contractors as well as the Navy.

Ferrite Indicator
The Ferrite Indicator is a simple, rugged, non-destructive inspection instrument developed for laboratory, shop and field use. The GO, NO-GO feature permits instant acceptance testing of austenitic stainless weld metals. The Indicator requires no external standards, no adjustments, no visual readings and is unaffected by position. It performs equally well on sheets, plates, rods, irregular shaped objects and individual parts of complex components. It is effective in locating areas of high or low Ferrite content heterogeneous products.
