These units are specifically designed for use in sea water and other very demanding environments including some corrosive liquids. The LWU61X displacement transducers are made of welded 316 stainless steel and have a thru bore. Because of their heavy duty construction, these units are suitable for the most rigorous applications including 10 years submersible in seawater at a depth of 7500 ft. (2300 m).
The armature is loose fit in the bore of the LVDT and is attached to the moving point by a male thread. Non-magnetic fluids enter the armature tube without affecting the operation on the transducer. In addition, this thru-hole design helps overcome the problems of marine growth. All Series LWU61X displacement transducers are shipped with traceable calibration certificates.
