The Series LWU is a family of submersible LVDT displacement transducers available in either DC or AC versions. These units are specifically designed for use in sea water and other submersible environments, including many corrosive liquids. The LWU Series features unguided armatures with stroke lengths from 0.5” to 4” and linearity of +/- 1%. Operating temperature is from -40 to 140 deg.F.
The LWU60X is an AC/AC unit with v/v output. The LWU61X and LWU65X are DC/DC units with outputs of +/-5 Vdc or 0-10 Vdc and 4-20mA, respectively. The LWU units are made of 316 stainless steel, and are fully welded. The heavy duty construction makes these units capable of enduring the most rigorous applications including 10 years submersion in seawater at a depth of 7500 ft. (2300 m). The free unguided armature design allows non-magnetic fluids to enter the transducer body without affecting the operation of the transducer. In addition, this thru-hole design helps overcome the problems associated with marine growth.
